Calcium borate Usage And Synthesis

Chemical Properties

white powder(s); prepared by fusion of CaCO3 and B2O3; used as a flux in metallurgy, in fire-retardant paint [MER06] [STR93]

Uses

• Calcium metaborate can be used as an additive to improve the performance of nickel-metal hydride batteries.
• It is used as a precursor to synthesize calcium hexaboride (CaB₆) by electro-reduction that can be used as high capacity anode for aqueous primary batteries.
• It can also be employed in the preparation of calcium-doped borate glass for thermoluminescent dosimeters (TLD).

Flammability and Explosibility

Not classified

Agricultural Uses

The calcium salt of boric acid is called calcium borate. Colemanite is a source of calcium borate, (Ca₂B₆O₁₁·5H₂O),from which boron is extracted. It can also be added to overcome boron deficiency.
