wholesale fashion pearl jewelry The diamonds that are used as treasures by the people of our earth, in addition to being very beautiful, there is a more important feature, which is its hardness. So far, diamonds are still the hardest natural substances that have been found on the planet. Its Mo's hardness has reached 10. Therefore, diamonds can not only be used as jewelry collection, but also can be widely used in various industries. It has relatively high practical value. Essence
In the high temperature and high -pressure earth, carbon elements will form a special crystal. Each carbon atom in the crystal will form a common price bond with the 4 carbon atoms next to it, as shown in the figure below.
The type of crystal is called diamond structure, which is the natural diamond before polishing. There are 4 outer electrons in the carbon atom. From the above figure, we can see that all outer electrons in the diamond crystal are used for the formation of covalent bonds. Therefore, there is no free electron in the diamond crystal. It becomes very large, and at the same time makes the diamond not have conductive properties.
The question is now. Diamonds are the hardest substances on the earth. If you use a hammer to smash the diamond, will the diamond broken? I believe few people may have done such experiments, after all, diamonds are so valuable. But in general, we will think that because diamonds are much harder than hammer, the diamond will not be broken after this hammer is smashed. Maybe on the hammer, it will be prone to a delant by the diamond.
But the fact is not the case. If you really do this, you will see very depressed, and a little hard, the diamond will be smashed by the hammer.
It is obviously the hardest material in the world. Why is it so vulnerable? This is because although the diamond is the highest, its toughness is very low. Toughness, also known as brittleness, is a physical indicator for objects to resist rupture. The higher the toughness of an object, the more difficult it is to break. It should be pointed out that the toughness and hardness of an object are two concepts with completely different.
Is when the diamond is strongly impacted, the crystals inside it will crack along a certain crystal direction, which will become a bunch of smaller diamonds, which is what we call "smashed".
but this is not to say that the hammer is stronger than the diamond. If you press the hammer on the diamond slowly, then no matter how powerful you use, the diamond will not be broken, and the hammer will be with As we imagined before, a delant was pushed by the diamond.
The is said to have done an experiment in a Japanese company that placed the artificial diamonds made by the company on the steel plate, and then slowly pressed the roadside machine from the top. Shengsheng roller. It can be imagined that if the roller in the experiment is faster, it may be another result.
In summary, don't think that the diamond is the hardest is invincible, in fact
wholesale jewelry stores in usa Diamonds are not the hardest material in the world. This substance is harder, and it is difficult for man to destroy it

wholesale online shopping international shipping jewelry Now the hardest material in the world is carbonide, and its hardness is 200 times that of steel, which is three times that of diamonds, but it is very unstable.
wholesale jewelry cad designer Yes. Because of its special chemical structure, he is the most stable chemical bond structure, becoming the hardest material.
wholesale jewelry dealers Diamond itself is composed of carbon atoms. It has a strong hardness. The hardest thing in the world is a substance composed of carbon atoms.
