Material testing center.
Zhou Qing gave a report on ‘Carbon-Silicon Crystal’.
Everyone looked at the 'carbon silicon crystal' on the screen and was fascinated by it.
‘Carbon-silicon crystal’ is a kind of light-transmitting crystal particle, which naturally exhibits a regular polygonal structure and has colorful lights when illuminated by light.
As researchers in materials science, they naturally know that the colored light appears because it contains other impurity elements.
Even so, it is very remarkable to be able to form such a structure and emit colored light, and it can be described as beautiful.
Wang Hui and Zhou Qing discussed it and thought they had found the 'target'.
They don't know where the materials come from or what kind of research they are doing. They are just testing and analyzing the materials, and the other parts are just burnt pieces, and there is nothing that needs attention at all.
After the goals are determined, the laboratory assigns work.
In one day, the laboratory completed the basic testing of carbon-silicon crystals, and Wang Hui immediately submitted the report and sent it to Wang Hao.
At the same time, he also filed an application to obtain more materials for subsequent more complex testing.
Strong S-wave research base.
At the bottom of the hill is a row of temporarily built houses. Wang Hao is sitting in one of the small houses. The small house is only a dozen square meters and is also his temporary office.
Although the environment is very simple, all necessary equipment is available, and it does not affect the work.
Wang Hao stared at the computer screen, checking the latest report. He frowned slightly and looked confused, recalling what Wang Hui said just now.
"Wang Hui said... found what I was looking for? What was I looking for?"
"I do not know how?"
After conducting the experiment, the experimental team dug out the black powder that participated in the reaction underground.
Those are the residues after the soil comes into contact with the ultrasonic S-wave area. I sent the residues to the material testing center just to let them do basic testing, hoping to know what specific reaction occurred.
In fact, Wang Hao did not expect to detect anything.
The soil itself is very complex, with various elements and chemical components. Complex thermal reactions will also cover up a large number of traces, making it difficult to obtain anything by detecting residues.
Wang Hao opened the report with doubts and knew what Wang Hui was talking about.
"Carbonite crystal? Moissanite?"
"Similar to diamonds and diamonds..."
This is a wonderful discovery.
Moissanite is also called moissanite, which is natural silicon carbide. Natural moissanite is a mineral discovered in meteorites by Henri-Moissan in 1893 and named after him.
Since Henri Moissan proved that he had never used artificial SiC to prepare samples, the doubt that artificial SiC was involved was eliminated.
Since then, the scientific community has successively discovered natural SiC in meteorites, kimberlites and other different types of rocks. However, as native natural SiC, it is only found in meteorites and kimberlites.
In the industry, there is a kind of artificial silicon carbide, called emery, which is a hexahedral granular material that has been widely used in the construction industry.
Whether it is naturally occurring silicon carbide or artificially produced silicon carbide, it generally appears as black particles or powder. Natural silicon carbide is very similar to coal and is certainly far from 'beautiful'.
The silicon carbide in the report is a transparent crystal with a regular polyhedral structure. After magnification, it looks like a polished diamond. When illuminated by light, it looks like it exudes colorful light.
"It looks really unusual."
"This should be due to the discovery of new substances, caused by reactions in the strong S-wave region?"
"Carbon-silicon crystals...perhaps just like elemental carbon, which takes on different forms in nature, such as graphite, charcoal, diamond..."
“Silicon carbide is also okay?”
Wang Hao frowned and thought, shook his head, and continued to read the report.
The report contains basic data on moissanite. There are two very outstanding characteristics. One is that the chemical properties are stable and conventional chemical reactions will only occur at high temperatures.
The above shows a combustion temperature data-above 3200 degrees Celsius.
This is very amazing.
Burning, not melting, carbon and silicon have very high melting points, but the melting point is measured under vacuum. Under normal circumstances, as long as a certain temperature is reached, carbon and silicon will react chemically with the air.
Carbon naturally burns.
The current carbon-silicon crystal can only react with air to cause combustion when it reaches 3200 degrees Celsius, which can be described as incredible.
The report also pointed out that "during the combustion process, a very high amount of heat is released, which is more than twenty times higher than the heat released conventionally."
This is only an estimate.
Because there is not enough material for research, experimental testing cannot produce accurate results.
Wang Hao looked at the data and knew that it must contain some unknown reaction, and it might be a very surprising discovery.
If it is a conventional chemical reaction, the heat released when a carbon atom and two oxygen atoms are combined and burned can be calculated.
Now the heat has directly increased by more than 20 times, which is obviously not a normal situation.
The second thing worth noting is the hardness. “The Vickers hardness of moissanite exceeds 140GPa.”
This is also an amazing statistic.
The Vickers hardness of silicon carbide ranges from 28 to 34 GPa, and the Mohs hardness ranges from 9 to 9.5.
In the definition of Mohs hardness, the hardest material is diamond, with a hardness index of 10.
Compared with diamond, there is still a certain gap in hardness between silicon carbide and silicon carbide. However, the hardness of the newly discovered silicon carbide crystal has exceeded that of diamond, so it can no longer be measured by Mohs hardness.
Vickers hardness is a direct measurement. The Vickers hardness of diamond exceeds 98GPa, making it the hardest natural substance on earth.
The Vickers hardness of carbon silicon crystal exceeds 140GPa, which can also be described as incredible.
This chapter is not over yet, please click on the next page to continue reading! "This discovery is indeed amazing, no wonder Hui said he found what I was looking for..."
"The target I'm looking for?"
Wang Hao smiled and shook his head. He did not expect such a major discovery at all.
After reading the report, he asked more black powder to be sent to the material testing center and continued to have Wang Hui's laboratory conduct testing.
Moissanite must continue to be studied in depth, its composition structure, and its special chemical properties.
There must be some unknown things in it, and it is probably related to the special characteristics of strong S waves.
…
After adjusting the equipment, the ultrasonic wave research team conducted a second experiment.
The adjustment of the equipment is mainly for the release direction.
Although it is just an adjustment of the direction, it is actually very complicated and involves a lot of calculation problems. It is not just about tilting the device at an angle, but also making certain internal corrections.
Of course, the process is not that complicated.
So the second experiment started soon. With the data from the previous experiment, the research team was very confident in releasing the super-S wave zone above the earth's surface.
After turning on the equipment, they waited for information from the team looking for the hyperwave area.
This experiment was very similar to the last one, with more than a dozen helicopters taking off to search. However, because there were not many internal changes, the release distance would not be much different, so the search was relatively simple.
The team only waited for about five minutes before learning that the strong S-wave area had been found.
The strong S-wave area was found in a flat area, about three meters above the ground, and part of it below the ground.
This also caused the surroundings to still be filled with smoke.
After the helicopter approached the super S-wave area, it landed in the distance. The personnel on top also slowly approached. They took close-up photos near Shili, and the thin black layer in the middle could already be seen.
"It's a thin, flat layer."
"The reaction below the ground was violent, and a lot of smoke was emitted."
"The surrounding temperature is very high and we can't get any closer..."
The on-site personnel made a report.
Although it has not been able to detect it at close range, strong S-wave areas have been discovered above the ground, and the experiment has made great progress.
The research team immediately knew what to do next.
They first shut down the device and then determined that no further adjustments would be made to the device.
