I Am the President of the University

"Everyone, please be quiet and listen to what I have to say."

The noisy sound disappeared instantly. Huang Jie looked at everyone with a smile and said loudly: "We have prepared the same high-quality silicon nitride powder as Ube Company. Logically speaking, this is enough to meet the domestic demand for silicon nitride ceramics. Okay, but is this enough?”

"I don't think it's enough!" Huang Jie shook his head.

"There is no eternal technology, but there are transcendences and subversions time and time again."

"If we are content now, it won't be long before UBE will develop higher-quality silicon nitride powder." Huang Jie's words are not sensational. As long as you stop and take a rest in this technology research and development track, you will be ignored. Beyond the past.

It is no exaggeration to say that it is a miracle that China is so far behind that it can overtake in corners.

Because all parties are running on the same track, especially when the other party is still dozens of steps ahead. In this situation, it is very desperate.

Huang Jie believes that the UBE company in this country will definitely not stop technology research and development.

Therefore, they cannot stop or relax.

"We will continue to research and develop, prepare silicon nitride powder of higher quality than our country's UBE company, and become No. 1 in this field!"

He looked around at everyone in the laboratory, his eyes burning with fire.

“We’re the best team, everybody is.”

"Since we can prepare silicon nitride powder of the same level as Ube Company in two months, we can also spend another two months to surpass Ube Company!"

"I believe you can do it!"

Huang Jie's words were like an inspiring speech, which made many researchers excited.

\\bMost of the members of the New Structural Materials Laboratory are under 40 years old, and all members are young scholars. At this age, they have not been completely smoothed by society, and they still have a bit of edge.

Although China's comprehensive national strength ranks second in the world, it still lags behind countries such as Japan and the United States in various advanced and sophisticated fields.

As a scholar, especially a patriotic scholar, no one can refuse to achieve No. 1 in their own field.

The researchers who had been injected with chicken blood continued to devote themselves to the research, but Huang Jie looked at the time and saw that there was still a while before getting off work, so he simply walked outside the laboratory and called the principal to report the good news.

After chatting briefly for a few minutes, Huang Jie turned around and walked a few steps when he saw a figure that surprised him.

"Old Wu, is something wrong?"

Wu Yucheng would definitely not stand outside the laboratory for no reason. With a little thought, he knew that the other party was waiting for him.

"Old Huang, let's talk next to you?"\\b

Huang Jie looked at the anxiety on the other person's face. Although he was confused, he nodded.

"good."

The two of them walked a few steps to the side corridor. After they were far away from the laboratory door, Wu Yucheng no longer concealed it and said with a wry smile: "Old Huang, it is not easy for us to prepare silicon nitride powder of the same level as Ube Company. It is based on our previous cooperation with Ube."

"This is already the limit. It's not easy to go beyond it!" Wu Yucheng had a little resentment in his tone. He felt that Huang Jie's words just now were too hasty.

Of course, subsequent technology research and development must continue, but it should not be too eager. It should be done slowly and steadily.

Surpass UBE in two months? ? ?

This step is too big, and it will easily break the egg!

Huang Jie asked: "Do you think we can't do it?"

Seeing Wu Yucheng's silent look, he sighed inwardly. When he invited Wu Yucheng, he resolutely chose to return to China, but now it seems that he was too safe.

"Old Wu, I know that two months is indeed a bit hasty, but if we don't try, how will we know that we can't do it?"

“It only took the impoverished New China 5 years to develop the atomic bomb, and as for the hydrogen bomb, it only took 2 years and 8 months!”

Huang Jie looked directly at Wu Yucheng and asked in a deep voice: "Seniors can create such miracles, why can't we do it?"

“The word ‘cannot do’ has never been found in the dictionary of Chinese scientists!”

"We can reach Ube's level in two months, and we can surpass them in two months."

"This... is just..." Wu Yucheng looked troubled, "Of course I only hope that I can do it, but can I really do it?"

"That's Ube Company." Wu Yucheng said in a low voice.

There are six preparation methods for silicon nitride powder, namely: direct nitridation method of silicon powder, carbothermal reduction method, thermal decomposition method, sol-gel method, chemical vapor phase reaction method and self-propagating high temperature synthesis method.

Most manufacturers in China and even the world widely use the silicon powder nitriding method. The reason is naturally that this method is relatively simple, low-cost, and the technology is relatively mature.

However, the biggest drawback of this method is that the β phase content and oxygen content in the powder produced are high, which will be extremely unfavorable for the preparation of high-performance silicon nitride ceramics.

Students who have attended college should all know that the quality of silicon nitride powder can largely affect the final performance of silicon nitride ceramics.

High-purity silicon nitride powder is difficult to prepare using the silicon powder nitridation method. Among the six methods, only the thermal decomposition method can be achieved.

However, because its preparation process is relatively complex and strict, only Japan's UBE company in the world has the ability to mass produce it.

It is no exaggeration to say that UBE is the dominant company in the field of silicon nitride powder.

This is why Wu Yucheng is troubled.

"Of course!" Huang Jie replied to Wu Yucheng like he was replying to Qian Yang.

"\\bOld Wu, believe me and believe in our team." He patted Wu Yucheng on the shoulder and walked directly towards the laboratory.

It's okay to have two voices in the laboratory, but as the deputy director, Wu Yucheng should have a united front to support him.

"Is it really possible?" Wu Yucheng murmured.

Looking at Huang Jie's back, Wu Yucheng knew that the other person was a little disappointed.

Maybe I was too careful?

As for Huang Jie, who returned to the laboratory, he came to the operating table as if nothing had happened and started the next round of research attentively.

In this laboratory, anyone can panic, but not him.

"Do a few more sets of experiments and see. \\u001d" Huang Jie thought to himself and began to instruct the team members to start operations, while he stood aside and watched the experimental reactions.

The principle of the thermal decomposition method is to react sicl4 with excess anhydrous ammonia in 0°C dry ethane to generate solid siCl

2 orsi

4. Subsequent precipitation of the generated material and nh4cl.

It is heated in a vacuum environment to remove nh4cl, and then heated in a high-temperature inert gas to obtain silicon nitride powder.

These steps seem quite simple, but the difficulty lies in how to obtain high-purity imino silicon and amino silicon.

Several sets of experiments passed, and the time was approaching noon. Looking at the data in the experimental report, some parameters were even worse than the previously successfully prepared set.

Huang Jie was not discouraged, but told the researcher beside him: "Xiao Zhao, collect all these data, and change some quantities in the afternoon to continue the experiment."

Many students may not know that scientific experiments are not as sophisticated as outsiders imagine, but rather find the path to success through constant trial and error.

Ten years is like a day, no exaggeration.

Those who can persevere are either crazy or on the altar of god!

ps: Sorry, it’s not easy to write about technology, because I have to change the previous article, so I can only make a single update, and then resume the two updates after the changes are completed and released.
