Chromium Diboride CrB2 Powder CAS 12007-16-8

About Chromium Diboride CrB2 Powder:

Chromium boride is a compound composed of chromium and boron, usually as a black powder or lump. It is a transition metal boride, belongs to the VB group, and is a kind of high-hardness material. 

Chromium boride oxidizes easily in air, so it must usually be stored in an inert gas or vacuum. It has a high melting point and hardness, which exceeds the common metal materials such as copper, nickel, iron, and so on. The strength and hardness of chromium boride decrease with the increase in temperature, but it can still maintain a fairly high hardness at temperatures above its melting point of 200 ° C. 

Chromium boride is mostly used in the industry as an abrasive or abrasive. It can be utilized in the production of cutting tools and wear parts. Due to its high hardness and melting point, it is an ideal wear-resistant material that can manufacture high-temperature bearings, high-speed cutting tools, etc. In addition, chromium boride can also be used to create protective coatings to enhance the material's corrosion resistance and oxidation resistance. 

In theory, chromium boride's physical and chemical properties are affected by its crystal structure. Under different temperature and pressure conditions, chromium boride can form different crystal structures, including orthogonal, monoclinic, and cubic structures. These different structures may have different effects on their physical and chemical properties.
