Calcium metaborate product introduction
Molecular formula: CaB2O4
Properties: white crystals.
Dissolution: soluble in water, enoic acid, water-soluble and alkaline.
Uses: Calcium metaborate is used to make alkali-free glass. It has superior performance than boric acid. It can increase tensile strength, increase resistivity, and reduce boron volatilization. It can be used as a component of fire-resistant coatings and anti-rust coatings. It is also used in gasoline, diesel and other fuel oils to improve efficiency. Used in lubricating oil to reduce friction, and at the same time as a raw material for antifreeze. In addition, it is also used as a catalyst, preservative, and bactericide in the chemical and pharmaceutical industries.
