As a rare and valuable item, diamond has been an important symbol of wealth since ancient times. In nature, diamonds are buried deep under the ground with very little mineral deposits. It is this rare diamond that has the unique characteristics of the world: it is the hardest ore in nature. This characteristic of diamond makes it have a wide range of social uses: some people put it in jewels such as glittering rings and earrings to symbolize the unyielding love; some made it into a sharp diamond for cutting Steel, glass, etc.
However, diamonds with such scarce reserves are far from satisfying the huge demand of society. People who are eager to have diamonds often naively think that if diamonds can become a large number of items one day, how good!
In 1893, the French Academy of Sciences announced an inspiring news: the French chemist Mowa Sangdi developed synthetic diamonds!
For a moment, this explosive and great news spread throughout France and spread all over the world. People were sensational, France was sensational, and the world was sensational! Mowasang became the focus of the news media and became the producer of huge wealth in people's minds. In France, some people even called him "the world's richest man."
Before the invention of synthetic diamonds, Mowasang was already a well-known French chemist. In 1886, Moissan first prepared elemental fluorine. 6 years later. He invented the high temperature electric furnace. However, Mowasan has not been swayed by flowers and honors. On the road of science, he still continues to advance.
On one occasion, Moissan was preparing for a chemical experiment that required a special instrument with diamonds. This kind of equipment is very expensive, so the assistants in the laboratory are more and more caring.
In the morning, Mowasang came to the lab to prepare for the experiment. At this time, all the instruments were ready, and the expensive equipment with diamonds could not be found. Strange, how could it suddenly disappear?
The assistant suddenly screamed: "Ah? The door seems to have been smashed! Is there a thief?"
Mowasang looked at it carefully, but the door lock was obviously opened. Before entering the laboratory, no one noticed. That said, the thief looked at the expensive diamond.
This accident gave Mowasang a thought: "Natural diamonds are so rare and expensive, how good it would be if you could make diamonds by hand!"
But this is easy to say! As a chemist, Mowasan is most clear in his heart: "It is a beautiful myth." To make diamonds, you must first understand the main points of diamond and understand how it is formed.
After reading a lot of information, Mowasang learned that the main part of diamond is carbon. As for how it was formed, the results of research in this area are few, and only Debray has proposed that diamonds are formed under high temperature and high pressure.
Then Mowasang thought that to make diamonds artificially, there must be raw materials for processing. What kind of material is appropriate? No one has ever tried this aspect. It seems that everything has to be explored by itself.
Once, organic chemist and mineralogist Charlie Friedel made a report on meteorite research at the French Academy of Sciences, and Mowasan participated.
In the report, Charlie Friedel said: "The meteorite is actually a large iron block, which contains the first diamond crystals."
When I heard this, Mowasang suddenly thought that there is always a very small amount of diamond crystals in the graphite ore. So, can diamond crystals be formed during the formation of vermiculite and graphite ore?
Thinking of this, Mowasang’s idea of ​​making synthetic diamonds appeared in his mind. He said to the assistants: "The main part of diamond is carbon. The meteorite contains vector diamond, and the main part of the meteorite is iron. Our experimental plan is: turn the program over, melt the iron, add carbon, make the carbon Under the high temperature and high pressure of the crucible, it can be seen whether diamond can be generated."
The first experiment in the history of artificial diamond production began. There is no precedent, no experience, no guidance from others, everything is like exploring the road in the dark. The first time I failed, I carefully summed up the experience and found out the crux of the problem. I came back for the second time... After countless repeated explorations, Mowasang’s lab finally burst into an exhilarating cheer, everyone tightly Embracing together: Success!
Since then, synthetic diamonds have been born and are increasingly playing its indestructible power in social life.
