CaB6 Calcium Boride Powder

CaB6 Calcium Boride Powder

There are many compounds among B-CA, but the common and relatively stable one is CaB6. Therefore, calcium boride mainly refers to calcium CaB6.

The common structure of hexboron compounds is CsCl structure. The difference is that B6 octahedron takes the place of Cs. Due to the strong covalent bond between B-B, it has the characteristics of high melting point and high hardness. Its physical and chemical properties are quite stable, in air calcination, CaB6 of sub-micron grade will appear after 800 degrees Celsius heat gain, not easy to oxidation, CaB6 is generally insoluble in hydrochloric acid and sulfuric acid, so technically to remove impurities by hydrochloric acid, but CaB6 is soluble in nitric aci.
