Can a diamond be artificially made at high temperature and pressure, is it the same as a natural dia

There are actually two kinds of diamonds, one is artificially made and the other is naturally mined, and there is a big difference between the twoHowever, it is very difficult and costly to mine diamonds naturally, and the risk is also very high, so many companies choose artificial high-temperature and high-pressure diamonds, but there is a big gap in hardness.

First of all, I believe that the first idea of a friend of a friend for diamonds is very hard, this thing is indeed very hard, especially the naturally mined diamonds, not to mention using them to knock walnuts, even if they are smashed stones, they are also a mineral, but because they are very beautiful and the content of the earth is very low, the difficulty of mining leads to the higher value of diamonds on the earth, which is generally used to propose marriage, and the price is also very expensive; So in fact, there are many companies that fancy the diamond market, after all, there is a great demand, and the value is also highHowever, the cost of mining natural diamonds is very large, so I began to think of artificially making diamonds in this way, and finally succeeded in coming up with high temperature and high pressure to make artificial diamonds.

This kind of high-temperature and high-pressure artificial diamond is actually a bit different from the effect of naturally mined diamondsIt's just that because of the continuous improvement of the company's factory and the beauty of the processing, it is almost impossible to see that there is a big gap with the appearance of natural diamonds when buying, after all, to make money, it is difficult to pass the first level of appearance; But there is indeed a big gap in hardness, how to say, simply put, it is to make artificial diamonds and natural diamonds at high temperature and high pressure to knock each other hard, and the broken ones must be made of artificial diamonds by high temperature and high pressure.

According to the experiment, if the hardness coefficient of a natural diamond is set to 10, it is possibleThen the hardness coefficient of artificial diamonds made by high temperature and high pressure is only about 8, and it is a relatively well-made artificial diamond, which is reduced by two points, and it can be seen that the hardness gap between the two is large.

No, its biggest feature is that it has the highest hardness and a strong refractive index, rifampicin is used in the eyes in the light, which is dazzling. However, its surface is similar to glass, crystal, and man-made diamonds, making it difficult to distinguish. Accurate identification depends only on instrumental measurements, while simple identification can be done by means of a thermal conductivity test that simultaneously breathes on the diamond and other similar objects to be identified.

If the diamond is a recognizable diamond, the condensation mist on its surface should evaporate faster than the mist on other objects.

This is because diamonds have high thermal conductivity, and when you look at the reflected light, you can observe a fine frosted reflection with bright crystals on the diamond's waist with a magnifying glass. This feature of diamonds is unique, look at the growth point. Observe under a magnifying glass.

The crystal surface of real diamonds always has grooves and triangular growth points, but these features are not visible in fakes, there are three kinds of counterfeit diamond-like products, ordinary glass containing alumina due to the increase in refractive index and dispersion.

It is easy to be mistaken for, but its hardness is low, imitation artificial zirconia, high hardness, good refraction, but when it rotates, it reflects more colored light, and compared with the real product, it only reflects faint yellow and blue light when it rotates, so there is a clear difference between the two. In fact, natural diamonds form more than 100 kilometers below the earth's surface and then rise to the surface with geological activity such as volcanic eruptions.

High temperatures and pressures in the earth's mantle crystallize the carbon into diamonds, occasionally encapsulating the surrounding dust or liquid impurities, which often contain small amounts of sodium, potassium, and other minerals that can reveal their environmental information. Natural diamonds can be divided into diamond types and diamond types, the main difference between the two is the nitrogen content, his type diamond is extremely pure, and there are few nitrogen impurities, he only accounts for 2 of natural diamonds.

Regarding the question of whether artificial diamonds can be made at high temperature and high pressure, and are the same as natural diamonds, I will explain here today.

Artificial diamonds created by high temperature and high pressure are different from natural diamonds, and natural diamonds contain natural ingredients that cannot be artificially created.

Of course it is different, although they are all carbon, and the structure is the same, but artificial diamonds are easy to seep into impurities, and ** is relatively low, while natural diamonds can be said to be unique, it is a gift of nature that cannot be replicated.

It's not the same. Artificial diamonds are processed using human manufacturing techniques, but natural diamonds are formed by themselves, which is different.

The existence of natural diamonds in nature, the difference between artificial diamonds and natural diamonds.

Question 1: Why are diamonds afraid of fire Diamonds are carbon products under high temperature and pressure. Since it is pure carbon, many people say that it is afraid of fire. But since it is generated by high temperatures, can the average fire hurt it? What should be its ignition point?

A: When a diamond reaches gem quality, it is called a diamond.

Although diamonds are formed under high temperature and high pressure, they can still change their phase if the physical and chemical conditions change sufficiently.

In a pure oxygen environment, when the temperature rises to 700-800 degrees Celsius, it will burn, and the solid (phase) will change from solid (phase) to gas (phase), that is, the solid diamond will be transformed into gas (carbon dioxide).

In the air, diamonds need to be heated to 850-1000 degrees Celsius before they burn and turn into gas.

Because diamonds are made of pure carbon atoms, they are all turned into gas when burned without leaving ashes.

Question 2: Is a diamond ring resistant to high temperature Diamond is actually composed of a carbon element formed under high pressure and high temperature conditions in the deep part of the earth, so it generally has the ability to resist high temperatures.

Question 3: Which is more resistant to high temperatures, diamond or gold? Although diamonds have a higher melting point, the premise is that there is no oxygen, 3500 degrees. If there is oxygen, it will start to burn at a little more than 1,000 degrees Celsius and turn into carbon dioxide. After burning, even the scum is not left.

Gold has a melting point of more than 1,000 degrees, but when you heat it up, it becomes liquid, and when it is cold, it solidifies and it is still gold.

Judge for yourself which is more heat-resistant.

Question 4: Are diamonds afraid of high temperatures or fire? Carbon dioxide!

Absolutely. 。

If you don't choose me, I'm sorry for human life!

Question 5: Why do diamonds disappear when exposed to high temperatures Yes, when placed under the focal length of a convex lens for a long time, it will oxidize and produce carbon dioxide. After a long enough time, the whole diamond is gone.

Question 6: Will high temperature affect the brilliance of a diamond? The nature of the diamond is relatively stable and will not affect the sale.

Question 7: Can a diamond withstand a high temperature of 20,000 degrees It indicates the carat number of the diamond, which is also a score.
