Calcium boride

Synthesized by self-propagating methods, there are many compounds between B-Ca, but common comparisons

The stable one is CaB6, so calcium boride mainly refers to calcium hexaboride caB6.

The common structure of hexaboron compounds is CsCl structure, the difference is 86 octahedron

Instead of the position of cs, because of the strong covalent bond between B and B, it has the characteristics of high melting point and large bulk. Its physicochemical properties are quite stable. When calcined in air, the sub-micron level

The heat gain of CcaB6 will only appear after 800 degrees Celsius, and it is not easy to oxidize. CaB6--like

Insoluble in hydrochloric acid and sulfuric acid, so technically hot hydrochloric acid is used to remove impurity materials,

But CaB6 is soluble in nitric acid

Physical and chemical indicators

1. Calcium hexaboride is black gray powder or granule. The melting point is 2230C, the relative density is 2.33g/cm, and it is insoluble in water at 15C and normal temperature.

2. Silicon boride is a glossy black-gray powder with a relative density of 3.0g/cm, melting at 2200C,

The grinding efficiency is higher than boron carbide and higher than silicon carbide. They have the characteristics of insoluble in water, anti-oxidation, resistance to thermal shock, and resistance to chemical erosion. Especially with high strength and stability under thermal shock.
