应用
It is used in detergents, cosmetics, and enamel glazes. It is likewise employed to prepare buffer solutions in biochemistry, as a fire retardant, anti-fungal compound, in the manufacture of fiberglass, as a flux in metallurgy, neutron-capture shields for radioactive sources, a texturing agent in cooking, and as a harbinger for other boron compounds. The molten borax bath is useful for carbide coating process on metals. It is applied as an efficient metal-free catalyst for Hetero-Michael reactions in an aqueous medium.

备注
Incompatible with strong oxidizing agents and strong acids.
