Boron oxide can be widely used as a flux in the decomposition of silicates, a dopant for semiconductor materials, an acidic catalyst in organic synthesis, a refractory additive for paints, and a raw material for the preparation of elemental boron and various borides. Boron (≥99.999%) Chemicalbook is a liquid sealing agent for the manufacture of III~V group compound semiconductors (such as gall ium arsenide, gall ium phosphide, indium arsenide). In recent years, with the rapid development of the LED industry, the output of gal lium arsenide, the substrate material, has increased, and the demand for high-purity boron oxide has also increased.
