Chapter 629: Covalent structure of inner electrons, a new direction in materials science!(1/2)
After having enough materials, the measurement of moissanite progressed very quickly. It only took about three days for Wang Hui's laboratory to issue a very detailed measurement report.
The laboratory will continue to conduct subsequent measurements, but these are studies that require long-term follow-up.
The current report is very detailed.
The Super S-Wave Research Base quickly received the report, and Wang Hao also summoned many people to discuss it.
The detailed test report of moissanite is very unusual. It is similar to the previous report and shows abnormalities in physical and chemical properties.
"The abnormal physical properties are mainly reflected in the special high melting point, high toughness, and high hardness."
"This data goes beyond conventional structural logic."
From an atomic structure analysis, no matter how stable the atomic arrangement of silicon carbide is, the physical properties it exhibits cannot exceed those of diamond.
The covalent composition of diamond's carbon atoms is extremely perfect.
Carbon atoms have four covalent bonds.
In the atomic structure of diamond, carbon atoms are connected to each other in a tetrahedral bonding manner to form an infinite three-dimensional skeleton. It is a typical atomic crystal. Each carbon atom forms a covalent bond with four other carbon atoms in an SP3 hybrid orbit.
Form a regular tetrahedron.
If you want to go further, you can only create materials similar to graphene, which cannot be measured by simple bond composition.
The atomic structure of silicon carbide, which is composed of two elements: carbon and silicon, is relatively stable, but silicon atoms only have two covalent bonds on average. The atomic structure of the silicon carbide formed is obviously incomparable to diamond.
Because of this, diamond has a Mohs hardness of 10 and silicon carbide has a hardness of 9 to 9.5.
The hardness of moissanite is 1.5 times that of diamond. It can no longer be explained at the level of atomic order structure and molecular composition.
"Chemical properties also exhibit abnormalities, reflected in chemical reaction requirements and energy release that exceed energy logic."
"For example, burning."
"Silicon carbide combustion releases energy intensities beyond specifications, 25 to 27 times greater than conventional silicon carbide combustion."
"This is obviously not normal."
To put it simply, it means that the amount of heat released during the combustion process exceeds the specification.
The combustion of carbon silicon spar is the reaction of elemental carbon and elemental silicon with oxygen, which mainly generates carbon dioxide and silicon dioxide. If the reaction is not sufficient, carbon monoxide, silicon trioxide and other substances will also be generated.
Combustion is a fixed chemical reaction with a fixed chemical equation. The final heat generated can also be calculated based on the overall energy loss.
Now there is an energy release that is more than 20 times higher, and an explosive flame is formed in the process. The high temperature is obviously far beyond the normal range.
"Why is there such a situation?"
At the discussion meeting, Wang Hao explained the measurement report of moissanite and also asked everyone questions.
Participants included people from the theoretical group, several scholars in the fields of physics and chemistry, and several leaders and directors of the research group. The latter just attended the meeting and listened to the content.
It is difficult to give professional advice.
Yang Zhifen and Lu Zhen are both very outstanding experts in the fields of molecular chemistry and atomic physics.
Many people also looked at them.
In the fields of molecular chemistry and atomic physics, Yang Zhifen and Lu Zhen are the top experts present, and they can put forward very important opinions in the professional field.
However, the current situation is that the content of the test report has exceeded the normal scope.
Yang Zhifen and Lu Zhen both frowned, completely unable to understand why such a situation would occur.
Wang Hao also looked at the two of them expectantly, and at the same time looked at others expectantly. He held a targeted discussion meeting with the purpose of analyzing what specifically happened.
Perhaps for others, if they want to know the underlying reasons, they still need a series of experimental measurement results before further analysis and derivation can be carried out.
Wang Hao only needs an idea, a correct idea.
While many people were lost in thought, Wang Hao was leisurely playing with the 'big diamond' in his hand.
Among the manufactured moissanite, there are many "big diamonds" forming a regular polyhedral structure, the largest of which is even close to 9 centimeters in diameter.
The one in Wang Hao's hand is not the biggest, but it is the most beautiful among them. It seems to be mixed with other elements, making it emit various colors of light when illuminated by light.
He put the diamond in front of his eyes and looked at it carefully, and couldn't help but sigh, "It is indeed beautiful and suitable for jewelry..."
"Give it to Yingxue!"
Wang Hao has already made the decision to enrich himself, while others are thinking about the reasons for the abnormal physical and chemical properties of moissanite.
They quickly grasped the key point - the composition of atoms!
The analysis of the physical and chemical properties of any substance must ultimately be attributed to the composition of atoms and molecules. However, the physical and chemical properties of carbon silicon spar are so excessive that they cannot be explained by "molecular bonds" and can only be attributed to anomalies in the atomic composition.
.
"No matter how it is constructed, molecular bonds cannot have such a stable structure, nor can they have such excessive chemical properties."
"It can only be an abnormality in the composition of the atoms, or it can be understood that some kind of change has occurred in the atoms."
Wang Hao recognized this conclusion.
The discussion will continue research along the direction, and the theoretical team will consider what changes will occur after the electron layer of atoms is stripped away.
"The phenomenon of leveling up can be ruled out."
Helen explained her opinion, "Neither the carbon atoms nor the silicon atoms have been upgraded, and at the same time, the atomic nuclei have not changed."
"When we studied the upgrading of elements, we have discovered that atoms that return to the normal environment after magnetization will also return to their original state."
After Helen finished speaking her opinion, others started to discuss it, but no matter which angle they studied it from, they could not come to a conclusion.
This is because conventional physical and chemical content can no longer explain such an abnormality that exceeds the standard.
Ding Zhiqiang whispered to Chen Mengmeng, "It may be that some changes have occurred that are impossible to conventionally exist."
"Using conventional physical and chemical knowledge to discuss undiscovered phenomena will not yield results."
Chen Mengmeng nodded with deep sympathy, then his eyes lit up and he said, "Could it be like this? For example, carbon atoms and silicon atoms are combined together?"
"Or, the nuclei of carbon atoms and the nuclei of silicon atoms are combined together."
"They are not covalent bonds formed on the outside, but on the inside..."
Ding Zhiqiang followed his thoughts and asked full of doubts, "How is it combined? Two atomic nuclei..."
He couldn't figure it out.
At this time, Wang Hao's eyes suddenly lit up, and the correct feedback appeared in his mind, and he immediately said, "Is there a possibility that carbon and silicon elements are not bonded together by covalent bonds? Or it is not the action of outer electrons.
Molecular bonds hold them together?”
Chen Mengmeng was stunned when he heard this, and couldn't help but admired, "Teacher Wang and I thought of getting together."
"It really is."
Ding Zhiqiang was full of admiration for Wang Hao, "We just thought about it, and Teacher Wang said it. He must have been earlier than we thought."
The discussion continues.
Two atoms are not held together by molecular bonds, so how can they be held together?
Most people are frowning.
Chen Mengmeng thought of a possibility. She immediately raised her hand and said, "Is this the case? I'm just telling you what I think..."
She spoke with some hesitation, even she herself thought the idea was too horrifying.
Wang Hao said encouragingly, "This is a discussion meeting. If you have any ideas, please speak out."
"All right."
Chen Mengmeng said, "That's it. Strong S waves will peel off the electron layer of atoms, so is there a possibility that after the electron layer is peeled off, the carbon nuclei and silicon nuclei in close proximity will be affected by the strong annihilation force field in a fixed direction, so that
Some special form of combination..."
"Like the twin stars in the universe?"
"After returning to the normal environment, the electron layer returns and forms a stable structure around the two atomic nuclei."
"In this way, the silicon carbide molecule becomes a special atom with a carbon-silicon dual-nucleus structure, and the outer electrons are connected to other similar special atoms..."
After listening to Chen Mengmeng's explanation, everyone else's eyes widened in shock, and they subconsciously thought 'impossible'.
"There is no such substance in nature."
