应用
It is used as a flux, an acid catalyst and a chemical intermediate in production of boron halides, esters, carbide, nitride, and metallic borides. Boron oxide has shown a promising effect on glycerol hydrogenolysis to 1,2-propanediol. It is also an essential material for the preparation of cordierite ceramics from Talc.

备注
Storage container should be placed in a cool and dry place and away from direct sunlight. Storage area should be made up of corrosion resistant materials.
