Calcium borate (Ca3(BO3)2). It can be prepared by reacting calcium metal with boric acid. The resulting precipitate is calcium borate. A hydrated form occurs naturally as the minerals colemanite, nobleite and priceite.[citation needed]

One of its uses is as a binder in some grades of hexagonal boron nitride for hot pressing. Other uses include flame retardant in epoxy molding compounds, a ceramic flux in some ceramic glazes, reactive self-sealing binders in hazardous waste management,[1] additive for insect-resistant polystyrene,[2] fertilizer, and production of boron glasses.

Also it used as a main source of boron oxide in the manufacturing of ceramic frits that used in the ceramic glaze or ceramic engobe for wall and floor ceramic tiles.[citation needed]
