Description

Boron oxide is used as a flux, an acid catalyst and a chemical intermediate in the 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. It is actively involved in the production of borosilicate glass. It is an additive used in high-temperature lubricants and dopants in semiconductor materials.Boron oxide is used as a fluxing agent for glass and enamels and as an additive used in glass fibers. It is used in the production of borosilicate glass, the raw material of chemical heat-treatment dissolved boron, organic synthesis catalyst and dopants use in semiconductor materials.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
