Scholars in the courtyard.

Chapter 2324 This is Silicon
In the laboratory, Wang Manshan saw that two high-frequency induction furnaces were ready, and two operators next to him were debugging them nervously!

There are two backup power supplies nearby, just in case.

"Old Wang, Yang Bu said, trust your feelings!"

"It's okay to fail, don't feel any psychological burden!"

Wang Manshan nodded seriously, "I understand!"

"Do not worry!"

Finally, he added, "Please tell me the key points again, I'm afraid I can't remember them!"

Li Lei didn't mind and repeated the familiar operating procedures!
"I know, I know!"

Wang Manshan said he remembered it, and he kept repeating to himself, "Nine hundred degrees, not too high, not too low!"

"Nine hundred degrees, nine hundred degrees!"

As Wang Manshan muttered, the operator received instructions and began the experiment.

First, put the processed quartz stone powder into the crucible of the high-frequency induction furnace, and then add 6 parts of reducing agent.

A piece of bronze is placed in the high-frequency induction furnace on the right.

Everything was ready. Wang Manshan half squatted down and waved at Li Lei.

Instantly, the power turns on.

High-frequency alternating current begins to flow into the copper tube, and then induced current appears in the objects inside.

Under the operator's control, this induced current quickly enters the copper coil.

The high-frequency induction furnace started working. The harsh sound and the heat made Wang Manshan feel very uncomfortable, but he still leaned forward and watched carefully.

Mr. Peng and Mr. Chen were watching intently. Mr. Ye came up and explained to them.

"This is a high-frequency induction furnace. Simply put, it uses the heat released by itself to melt itself..."

“It acts directly on the inside of the object.”

"This method allows for rapid heating."

"However, safety is a major concern, and a safety assessment must be conducted after each use, and demagnetization must be performed before each use!"

"Also, the strength of the power supply must be guaranteed..."

Mr. Ye was talking on the side, and Mr. Peng and the other two were listening attentively.

Not only that, but others were also paying close attention.

Yang Xiaotao also added on the side, and Han Sanfeng waved his hand and asked someone to take careful notes.

The system-provided process will not tell you these things.

Because the system provides the process under the condition that everything is fully prepared, which is very different from the reality.

But what Mr. Ye said can be used in reality.

Maybe in a few years they can improve it, maybe a better high frequency induction furnace will be developed, but for now, these are all they can use.

"Something has changed!"

Li Hongfeng was standing by and saw the bronze in the furnace on the right begin to melt with flames, and everyone looked over there.

This is the suggestion made by Mr. Ye.

The melting points of some known special metals are used as standards to determine the gear position of the high-frequency induction furnace.

The melting point of bronze is around 800 degrees, which is just right for use.

They conducted several experiments in the early stage and were able to basically determine the required frequency.

This experiment was also done to be absolutely sure, otherwise it would have been a high-frequency induction furnace.

However, what made Yang Xiaotao regretful was that he failed to find any metal with a melting point of 900 degrees.

Even so, Mr. Peng and Mr. Chen, who were aware of the situation, nodded with satisfaction.

There are always more ways than difficulties.

Obviously, the nine departments have put some thought into this aspect.

Therefore, when the altitude rises to 900 degrees, it will depend on Wang Manshan’s eagle eyes and golden pupils!

"Team Leader Wang, it's 800 degrees, pay attention!"

Li Lei shouted and went straight to the high-frequency induction furnace to start working on it himself.

Wang Manshan nodded slightly after hearing this!
At this time, Wang Manshan stared at it without blinking, and even though sweat was dripping down his forehead, he didn't dare to touch it with his hands, for fear of missing the time!
At the same time, his hand slowly raised and then gently pressed down.

Every time he swung downwards, Li Lei beside him would increase the frequency a little.

As time went by, the frequency of Wang Manshan's hand waving began to slow down.

The people outside were watching anxiously, but they didn't dare to say a word. They just stared at Wang Manshan's every move!
Gradually, it got dark outside.

The lights in the laboratory were not on.

Just as everyone was waiting anxiously, they suddenly saw Wang Manshan stretch out his hand and press down quickly.

Li Lei startled and moved his hand, causing the button to turn a little.

The next second, Wang Manshan sat down on the ground, wiping the sweat from his face and laughing.

Li Lei quickly recorded the current frequency of the high-frequency induction furnace, and then asked someone to start turning over the boiler inside.

In this step, they need to be continuously reversed to allow it to fully react with the reducing agent.

At this time, Wang Manshan turned around and waved to the people watching outside with an affirmative smile.

In an instant, people around hugged each other, followed by cheers that lasted for a long time!

Mr. Peng and Mr. Chen were also infected by the crowd. Seeing everyone happy, they couldn't help but applaud.

Papapa

Applause goes to Wang Manshan, Li Lei and others inside, and also to those outside.

When the applause died down, Yang Xiaotao quickly reminded everyone, "Everyone, pay attention, we are not finished yet."

"Director Zhu, you need to be prepared for what's next."

Zhu Ziqing came out and shouted, "Please, Chief, please rest assured, Commander Yang, we are ready."

Someone from the Institute of Chemistry not far away came out immediately.

Seeing that everyone was ready, Yang Xiaotao said no more and watched the changes inside the induction furnace carefully!

According to the process requirements, crude silicon can be obtained after continuous flipping and sufficient reaction at a high temperature of 900 degrees!
It took more than an hour for the high-frequency induction furnace to finish the reaction.

After waiting for more than an hour, Li Lei took out the cooled boiler and cooled it quickly in accordance with the process requirements.

Yang Xiaotao walked quickly forward and looked at the crystals inside which had turned a little gray, with a look of relief on his face.

This form has already shown that the success is at least halfway achieved! The next operation belongs to the category of chemical reaction!

Yang Xiaotao looked at Zhu Ziqing, "It's up to you guys now!"

Zhu Ziqing nodded, "Understood!"

After saying that, Zhu Ziqing led his men to start wearing protective clothing, gloves, and goggles, and they were all wrapped up tightly!

Although it is cold outside, the temperature in the laboratory is not low. If you go in like this, you will probably sweat all over.

Zhu Ziqing looked at the people behind him, nodded, and led the group into the laboratory.

Take an inventory of the instruments and equipment inside, and after checking them, start arranging tasks!
In accordance with the process requirements, everyone put the obtained crude silicon into the reactor again.

Then another 6 reagents were injected...

Mr. Peng and Mr. Wang were watching from the side. Yang Xiaotao chatted with Mr. Ye for a while before coming over.

"Boss Peng, Commander, the next response will take quite some time, how about we go eat first?"

President Peng shook his head, "I'm not hungry, if you're hungry, go eat!"

Yang Xiaotao looked at Mr. Chen again, and Mr. Chen shook his head.

How can they have the heart to eat now?

If these two don’t eat it, then no one else will dare to eat it.

So everyone continued to wait outside.

This wait lasted until dawn the next day.

When it was daybreak outside, Yang Xiaotao heard some movement behind him. Turning back, he saw President Peng moving his hands and feet and walking towards him!

There weren’t many people present, after all, there was still work to be done.

Besides, Mr. Ye is old and can’t hold on any longer, so let him go back to the office and rest!

The remaining ones were Yang Xiaotao, Li Hongfeng, Mr. Peng and Mr. Chen, as well as the guards responsible for security in the surrounding area.

Seeing that Mr. Chen was still resting, Yang Xiaotao said to the guard on duty not far away, "Ask the kitchen to prepare some food. More!"

The guard nodded and walked away quietly.

President Peng came to Yang Xiaotao, looked at the busy scene inside, and then asked, "How long has it been?"

Yang Xiaotao looked at his watch. "Eight hours!"

"What's going on?"

Yang Xiaotao rubbed his face and nodded, "It went smoothly!"

After all, this is also the first on-site experiment.

The system only provides a process operation diagram for the process, and the specific situation still needs to be combined with reality.

Mr. Peng nodded, but his eyes were fixed on the laboratory technician in the room.

In this environment, persisting for such a long time requires not only physical support, but also a firm will!
Yang Xiaotao took out the cigarette box and found that there was only one cigarette left in it, so he put it back in his pocket.

"I didn't expect it to take so long!"

“Such a complicated reaction!”

President Peng stood with his hands behind his back, "This is what we say, what you learn from books is shallow, you have to practice it yourself to know it for sure!"

"If you don't try, you will never know where the gap is!"

Yang Xiaotao nodded slightly.

Still not prepared enough!

At the beginning of the reaction, the amount of reaction reagent required is too small, resulting in incomplete reaction.

When collecting gas in the second step, we found that the color inside was wrong, and there was still a lot of quartz powder left in the reactor.

Obviously, the experimental reaction is not thorough, which will affect the experimental results.

So everyone looked for the reason, and later found out that it was not the fault of the process requirements, but the purity of the reaction reagents was not enough and the amount added was insufficient.

After reconversion, the experiment was repeated and silicon tetrachloride gas was finally obtained.

The next step is the current operation, which is to add hydrogen into the reactor and heat it at high temperature to allow it to react fully to produce high-purity silicon and hydrogen chloride gas.

If you want to implement these simple steps in practice, you have to figure them out step by step!
The experiment was able to proceed smoothly, all thanks to Zhu Ziqing, the chemistry professor!
"Is this the end?"

President Peng looked at the people inside walking together, as if they were observing something.

Yang Xiaotao came to his senses and looked over, only to see Zhu Ziqing suddenly raise his head and wave at him.

"Success?"

Li Hongfeng also ran over when he heard the noise, very curious.

Not far away, Mr. Chen also stood up.

"I don't know, let's wait and see."

Yang Xiaotao stared inside and soon saw Zhu Ziqing walking out holding a reaction dish.

The four of them were busy waiting on the side.

"Minister Yang, take a look, is this high-purity silicon?"

Zhu Ziqing walked up to Yang Xiaotao, his voice full of fatigue.

The researchers behind him came out and helped each other take off their protective clothing, revealing their sweaty bodies underneath.

At this moment, the four people focused their attention on the small reaction vessel.

A small pile of blue-grey crystals.

It looks a bit like crystal, but much smaller.

Even when the sunlight shines in, it actually has a metallic color.

Yang Xiaotao carefully took the reaction dish, and his breathing became slow, as if he was afraid that it would blow away if he used too much force.

"This is, silicon?"

President Peng asked in a low voice.

Old Chen rubbed his eyes and looked carefully, trying to see if there was any difference from what he had imagined.

Li Hongfeng had no idea what this was, but since the three of them were looking at it, he came over to look too.

Yang Xiaotao compared the information with that in the ultra-pure silicon production process, and then nodded vigorously, "Yes, this is silicon!"

“Something that could bring about world change.”

After hearing this, Mr. Peng and the other two looked at each other in bewilderment.

If they hadn't seen it with their own eyes, it would have been hard to believe that this thing was extracted from the stone.
