Chapter 162: A bit rusty, wasted some time

The optoelectronics laboratory was much larger than their laboratory. It could perform preparation techniques like chemical vapor deposition, physical vapor deposition, and pulsed laser deposition, and also had X-ray diffraction (XRD) and various electron microscopes.

All of them were pieces of equipment Xu Qingzhou was familiar with.

"Junior brother, the BIO and BO have arrived." Gong Yunfei had already brought over a material box from the side.

Wang Wei pointed to the white instrument in front and asked with a smile, "Have you come into contact with this equipment before?"

Xu Qingzhou said, "I've seen the process in books."

Although he could operate it with his eyes closed, he was just an undergraduate; if he said he was very proficient, that would be a ghost story.

When it came to experiments, Wang Wei's expression became serious. He pushed up his glasses and said, "Then I'd better do it, and you can observe from the side."

"Hmm."

Read! {

Xu Qingzhou nodded in agreement.

"I'm just here to drink some water. Don't worry, I can definitely produce the crystals you need today!"

Xu Qingzhou smiled helplessly and said, "Senior brother, how about I do it instead?"

Before leaving, Wang Wei gave him a detailed rundown of the laboratory's precautions.

Hey, junior brother is pretty good; he didn't forget to sieve first.

Wang Wei, meanwhile, was staring intently at every step Xu Qingzhou took, so he could remind him in time if Xu Qingzhou made a mistake.

He could understand this competitive psychology, but the problem was that he was in a hurry. If it failed again, he would have to wait several hours, wasting time.

Wang Wei's mouth twitched. The speed was almost twice as fast as his, and accurate too.

Large-scale crystal manufacturing takes weeks or even months, but fortunately, the crystals Xu Qingzhou was using for this experiment were very small, though the process was still troublesome.

On this side, Xu Qingzhou had already finished the ratio weighing in a few quick steps and was preparing to melt it. He looked up and saw Wang Wei and Gong Yunfei staring at him.

BIO and BO, although these two substances weren't as highly corrosive as the battery solution used by Wang Wang Shixiong and his team, if a mistake occurred in the ratio, it could cause a blockage in some instrument. The equipment here was quite expensive, and Wang Wang Shixiong was also starting his project experiment in a few days; it would be troublesome if something went wrong.

Oh, right, because of the large density difference between BIO and BO, unevenness could easily occur during the mixing process, affecting the uniformity of the melt and the growth of the crystal.

He smiled shyly and said, "Sorry, a bit rusty, wasted some time."

After all, although these instruments and equipment were very valuable, talent was ultimately the priority. If an accident like a fire occurred, ensuring human safety came first, and the equipment second.

At noon, Wang Wei and the others went to eat, and Xu Qingzhou stayed behind to keep watch.

An hour later, Xu Qingzhou adjusted the temperature field of the crystal growth furnace to 750°C and turned on the stirrer to ensure uniform mixing of the raw materials and the discharge of bubbles.

Wang Wei's expression was complex. Xu Qingzhou's movements were skillful, methodical, and every step was quite precise—the kind that could be used as a teaching video.

Gong Yunfei came over to join the fun at this time, or rather, he actually wanted to "guide" this junior brother. He was a senior brother, after all; he couldn't compete in talent regarding theory, but practical operation should be stronger, right?

Xu Qingzhou knew that Wang Wang Shixiong was worried he would break the equipment.

Gong Yunfei said from the side, "Don't mind him. To Wang Wang Shixiong, these pieces of equipment are like his own wife, more important than his own life."

He nodded with a smile. Having a doctoral student who didn't need a salary helping him prepare crystals, he could actually be a bit lazy.

Wang Wei's expression stiffened. He coughed dryly and said with some embarrassment, "There was a small accident... it suddenly cracked during the crystal growth process."

When melting, the top-seeded crystal growth method involves introducing a seed crystal and controlling conditions like melt temperature, concentration, and flow to allow the melt to gradually crystallize and grow into a single crystal. Fast and accurate—this is called rusty? Gong Yunfei's mood was also quite complex; it was a mix of emotion and being hit hard. Is this junior brother a bit too heaven-defying?!

After saying that, he didn't waste any more time and started operating.

Wang Wei put on his goggles: "Junior brother, the plan and the ingredient list."

20 minutes passed.

After finishing these, Xu Qingzhou took off his goggles and sat in a chair reading the book on battery materials that Wang Wang Shixiong had left for him to pass the time.

Xu Qingzhou smiled and said, "I watched your operation just now and remembered it all." Wang Wei paused and nodded reluctantly, but couldn't help but urge, "Then I'll watch from the side. You must ask me in advance if there's anything you don't know."

So moving! Finally, there was a place that could reflect the role of this senior brother!

During the process, parameters like temperature gradient, melt flow rate, and pulling rate had to be controlled well.

What was the most common problem for a novice entering the laboratory?

He specifically emphasized the most important experimental rule—ensuring one's own safety.

Xu Qingzhou looked up and felt Wang Wang Shixiong was quite reliable. "Wang Wang Shixiong, has the crystal formed?"

Although the laboratory had an advantage in equipment, which could greatly reduce the crystal preparation time, from melt to crystallization, and finally to the final cutting and processing, it would take at least a dozen hours if no accidents occurred.

Precisely weigh the raw materials and mix them according to the stoichiometric ratio BIO: BO=1:3.

Beside him, Gong Yunfei was also stunned, with only two words in his heart: Professional.

Xu Qingzhou had written these steps very clearly in the plan he gave Wang Wei earlier. Wang Wei was preparing it, so he wasn't in a hurry and went to the lounge next door to read.

That's right, in front of the test bench, Xu Qingzhou took out the two oxides, BIO and BO, first performed a sieving process, and then started the ratio.

Xu Qingzhou changed into a spare white lab coat, put on goggles, and prepared to operate it himself.

Thus, the entire preparation experiment was more than half successful. Next was the long waiting time, which would take about 12 hours.

"But this equipment..." Wang Wei was still uneasy. Although Xu Xu Shidi Xu's talent was terrifying, experiments and practical operations were different. Just like him, someone who was often in the laboratory, had a complete and detailed ingredient list and plan, and still failed.

Wang Wei glanced at the ratio table and praised, "Tsk tsk, junior brother, you wrote it very professionally."

After weighing, the uniformly mixed raw materials were placed in a clean crucible for melting.

When the raw materials began to solidify, he introduced the seed crystal into the growth furnace.

"You're doing it yourself?"

Two hours passed, and Wang Wei walked in.

Xu Qingzhou handed over the document.

!.

Time passed second by second. At 1:30, Ren Xiaoling came to change shifts.

The remaining work was relatively simple: keep watch on the side. If the instrument sounded an alarm or cracks appeared on the crystal during this period, press the stop button to stop the experiment.

This would also mean the experiment failed and had to be restarted.

Of course, Xu Qingzhou was confident that this situation would not occur.
