Because synthetic green chalcedony is highly similar to natural green chalcedony, it will not appear in the spectrometer with a wide absorption band at the end of the red zone like dyed green chalcedony.

Qin Qiongwen has now synthesized green chalcedony, which means that if you want to distinguish the natural Zimbabwean green chalcedony, you not only need to identify and dye green chalcedony, but also have the technology to identify and synthesize green chalcedony.

If you can't do it, the chalcedony color identification will never be included in the chalcedony.

But at present, this technology is simply blank because no one has ever tried to synthesize cheap gems such as chalcedony.

The synthetic green chalcedony in Qin Qiongwen's hand is probably the equipment and material cost required to make such a small piece is enough to exchange for several baskets of natural chalcedony, and the scientific research fund required to successfully develop it can at least bring a truck of natural chalcedony.

The high cost and nearly zero economic benefits make no normal company devoted its energy to developing synthetic chalcedony.

However, Qin Qiongwen is different. She doesn't need to consider whether it can be put into the market after research and development, or whether it can make money. As long as it can prevent Song Tao and Yunshi Group from promoting the inclusion of green chalcedony appraisal into the industry standards, this technology will not be a waste.

Liu Xi asked: "Representative Qin, is this really the latest technology of the Baohui Association?"

Qin Qiongwen said frankly: "Of course, we welcome the conference expert group to take people to the factory to visit the synthesis steps and processes."

Liu Xi checked the schedule: "After five days later, at 2:00 pm, the fourth expert group has free time to verify. The specific situation depends on the arrangement. You can prepare first."

Qin Qiongwen nodded in agreement.

Then Liu Xi said to Song Tao embarrassedly: "Representative Song, if the technology of Representative Qin and Baoxie are fine, your opinion may not be able to pass the preliminary review."

"Hey, Team Leader Liu, don't hurry to draw a conclusion!" Song Tao quickly raised his hand and stopped her.

After being surprised, Song Tao quickly sorted out his emotions and analyzed rationally: "Isn't it just that the academic community has no technology to distinguish the synthesis of green chalcedony? Then let's just let it have it?"

Liu Xi was stunned for a moment, and then said in disbelief: "What do you mean is to overcome the technology in the short term? But the second branch will be held at most fifteen days apart, which is a bit unrealistic, right?"

"It's a piece of cake, nothing unrealistic." Song Tao said with a tough forehead.

"If it's reality, that's what it means!" Song Tao thought to himself.

The physical and chemical properties of synthetic gems and natural gems are very similar. Ruby, sapphire, emerald, etc. are usually completely transparent and can be distinguished from their synthetic products by observing the internal inclusions.

However, green chalcedony is a cryptocrystalline aggregate that is translucent to opaque, and there is no way to observe inclusions. Song Tao's strongest professor-level inclusion identification level is useless.

In this way, we can only hope to distinguish between spectral characteristics or microstructures, but the spectral characteristics of natural green chalcedony with different colors and different tones may be slightly different. How to distinguish them from synthetic green chalcedony?

Of course, Song Tao knew that there would be an appraisal method, but if you can complete the technical breakthrough in such a short time, it would definitely be a miracle that would be the same level as the men's football team's World Cup.

The following meeting was all about some clichés, so Song Tao had a little bit of a sudden experience: If the identification of the color of the chalcedony cannot be included in the national standard, then the agreement with Yunshi Group will naturally be invalidated, and 45 million funds will be wasted directly.

Sugut Mining has lost 100 million yuan in funds.

Yunshi Group's 45 million funds are gone.

Half of the only qualifications for the Hetian jade origin identification were also stolen.

——It’s really a heart-warming feeling, sharing together.

Thinking of this, Song Tao sighed, then stood on his chin, thinking: "If I can't solve this problem, I'm afraid the school will still go out to worship the sky."

Soon, the branch ended with Song Tao's misunderstanding. After Liu Xi announced the end of the meeting, personnel from other institutions left the conference room one after another, while Song Tao asked other personnel from Huachang Land University to leave the venue first and stay first.

Qin Qiongwen also tacitly asked Baohui's personnel to leave, and there were only two people in the conference room, Song Tao and Qin Qiongwen.

And the big pot on the conference table.

Qin Qiongwen shrugged at Song Tao with a paralyzed face. She pointed to the sample cavity of the large cavity press and said, "How is it?"

Of course, Song Tao knew that she was not asking about the sample accent, but synthesizing green chalcedony, but Song Tao had the kind of unyielding character. He was killed by Qin Qiongwen in just two rounds, and now he was suffocated to death.

He has never felt such a strong sense of frustration since he attended the internship.

So Song Tao pretended not to understand and said depressedly: "This pot is good, shiny and looks very thick. It has used very superb seamless welding technology and can probably be sold for a lot of money."

Qin Qiongwen held her forehead and smiled helplessly, "Who asked it?"

Qin Qiongwen took out the sample of synthetic green chalcedony again and said to herself: "This time, the synthesis of green chalcedony takes a long time and is extremely difficult. There are actually certain accidental factors for my successful synthesis."

"The composition of green chalcedony itself is not complicated. After reacting with several oxides, it is converted into a quartz aggregate under the participation of chromogenic ions in high temperature and high pressure. At the beginning, the initial oxide mixture cannot melt, and the synthesis product is extremely uneven. It is not until the pressure rises above 50kb and the temperature reaches 1400℃, the chromium ions successfully enter the crystal lattice..."

Although Qin Qiongwen only mentioned it casually, Song Tao immediately raised his ears and listened quickly. If he could understand the specific synthesis process, he might hope it would be bigger.

Unfortunately, Qin Qiongwen did not reveal any valuable information.

After playing with the synthetic green chalcedony for a while, Qin Qiongwen gently placed it in front of Song Tao: "You can take this sample back first. I will send more synthetic products to Huachang Di Dafang tomorrow and the next day."

Song Tao's eyes lit up and he said in surprise: "Are you so generous?"

"Who is generous to you?" Qin Qiongwen waved her hand and said, "It's just the rules of the conference. Besides, if you can post three SCI section 1 players within half a year and get out so quickly, I really feel a little regretful."

As he said that, Qin Qiongwen measured a very small gap with her thumb and index finger, as if she was solemnly declaring: My regret is really only a little bit.

Song Tao frowned at first, but when he heard Qin Qiongwen talk about regret, he couldn't help but be amused: "Why do you treat me as your opponent in the game?"

"Of course." Qin Qiongwen teased: "I thought you were at least a silver, but a pity..."

"Don't be a pity." Song Tao made a pause gesture and quickly put away the synthetic green chalcedony sample.

Then Song Tao left the conference room like a gust of wind, and before leaving, he said, "Director Qin, wait for my good news."
