What is the strongest stone besides diamonds, and is diamonds the hardest stones?

Diamonds are the hardest stones, and there may be harder objects on other planets!

In fact, there are harder just, not stones!

German scientists have synthesized in the laboratory a substance that is harder than diamond, and like diamonds, it is made entirely of carbon atoms. The article was published in the August 22 issue of Applied Physics Letters. The new material, known as the Diamond Nanorod Polymer (ADNR), was obtained by compressing a fullerene molecule (carbon-60) at 200 atmospheres at a temperature of 2226 at 200 atmospheres.

And fullerene itself is a molecule with a very stable structure. The structure and properties of this material have been studied at the European Synchrotron Radiation Laboratory in France. X-ray analysis shows that ADNR is denser than diamond and is more resistant to high pressures than all known materials.

Scientists say that the hardness of ordinary diamonds** is very strong atomic bonds between carbon atoms, and that ADNR is harder than diamonds because it is formed by the interlocking of nanorods. The material has a very wide range of industrial applications, and due to its ability to withstand high temperatures, it is more suitable for underground excavation or grinding of hard materials than diamonds, and it is also easy to produce on a large scale.

Diamonds are the hardest stones.

Diamonds are the hardest and simplest gemstones in the world, and they are cubic natural crystals made up of carbon. Its composition is basically the same as that of coal, pencil lead and sugar, and carbon crystallizes to form graphite (black) at high temperatures and pressures, and crystallizes into precious diamonds (colorless) at high temperatures, very high air pressures and in a reducing environment (usually a hypoxic environment).

A carat, or carat, is a unit of mass for a diamond. One calorie is equivalent to 200 milligrams, and legend has it that the weight used by early diamond traders to weigh diamonds was the fruit of the rice bean tree (carob), and one such fruit weighed about 200 milligrams. Because diamonds are essentially the same density, the heavier the diamond, the larger the volume.

The larger the diamond, the rarer it is and the higher the value per card.

Diamonds are the product of diamond finishing, the hardest and simplest gemstone in the world, which is a natural crystal with a cubic structure composed of carbon. Its composition is basically the same as that of coal, pencil lead and sugar, and the carbon element crystallizes to form graphite (black) at high temperature and pressure, and crystallizes into precious diamond (colorless) at high temperature, extremely high trace collapse pressure and reducing environment (usually a hypoxic environment).

Grading of diamonds

1. Color. The color grades of diamonds from high to low are D, E, F, G, H, I, J, K, L, M, N, among which D colorless diamonds are the rarest and most expensive, while most of the colors below K are faintly yellow and do not have too high value.

2. Cut. Diamond cut can be divided into five grades, in order of high and low, which are Exellent, Vertgood, good, Fair, and Poor.

3. Clarity. The clarity grade of diamonds from high to bottom is FL, IF, VVS1, VVS2, VS1, VS2, SI1, SI2, I1, I2, I3, with FL being the highest grade, and the diamond contains very few impurities and looks very pure.

4. Weight. The weight grades of diamonds are ,,, weight is size, and the larger the diamond, the rarer and more precious it is.

A stone and a diamond met in the mud circle.

One day, the diamond said to the stone, "Hey! Pebble, my status is higher than yours!

The stone said, "Why do you say that? I have my use, you have the role of your sedan chair!

What is there to quarrel about? At this time, Mr. Mike, who had been listening to the sidelines, said, "Don't make any noise.

I'll take the diamond to the king and see what it does. So the diamond was brought to the king. Soon after, Mr. Mike arrived.

He said to the stone, "The diamond was placed in the princess's crown." Now it's your turn to see what you're up to.

The stone was brought to the king. "Hey! Mike.

What did you bring me again? The king asked. "I brought you a stone.

Mr. Mike said. "What is the use of this stone? The king asked.

By the way, you can use it as a road! So the stones were paved on the road.

After a few days, the stone adapted to his life. Because he could see women's high heels, men's leather shoes, girls' single shoes, boys' sneakers, ......

Diamond ah And aluminum oxide - natural gemstone Diamond is the original state of gemstones He is a glass knife No more Thank you, landlord.

Diamonds are simply the hardest of nature. A lot of modern things are harder than it. Just look it up online.
