Do you know the basic knowledge and uses of calcium boride?

Overview of calcium boride
Calcium boride is a chemical mainly synthesized by means of carbothermal reduction and self-propagation. There are many compounds between B-Ca, but the common and stable one is CaB6, so calcium boride mainly refers to calcium hexaboride CaB6.
Calcium hexaboride is black-gray powder or granules. The melting point is 2230℃, the relative density is 2.33g/cm, and it is insoluble in water at 15℃ and normal temperature. Calcium boride is a boron-containing additive used as anti-oxidation, anti-erosion, and hot strength of dolomite and magnesium dolomite refractories. It is also used as a deoxidizing and degassing agent for high conductivity copper to improve conductivity and strength, and as a chemical agent for other chemical purposes.

 
The main application of calcium boride
1. Used as a boron-containing additive for dolomite and magnesium dolomite refractories to resist oxidation, corrosion and improve thermal strength.
2. Used as a deoxidizing and degassing agent for high conductivity copper to improve conductivity and strength.
3. It is used as a new type of anti-neutron material in the nuclear industry.
4. Used as a new type of semiconductor material in spintronic components with a Curie temperature of 900K.
5. Used as a raw material for the manufacture of boron trichloride (BCl3) and amorphous boron.
6. Used as a raw material for manufacturing high-purity metal borides (TiB2, ZrB2, HfB2, etc.) and high-purity boron alloys (Ni-B, Co-B, Cu-B, etc.).
7. It is used to manufacture a mixture of calcium-boron nitride (Ca3B2N4) and hexagonal boron nitride containing catalyst, and use to produce crystalline cubic boron nitride with excellent performance.
8. Used as desulfurization, deoxidation, and boron increase agent for boron alloy cast iron. 9. Used as desulfurization, deoxidation, and boron increase agent for boron steel.
10. Used as a deoxidizer for metal smelting.
