Boron is insoluble in water. The boric powder is soluble in boiling nitric acid and sulfuric acid, as well as most molten metals such as copper, iron, manganese, aluminum and calcium. Boron is present as a trace element in quartz ore. In the purification process of high-purity quartz sand, how to reduce the B content as much as possible is the key to the process. The presence of B lowers the melting point of quartz, and the number of used quartz crucibles is lowered, resulting in an increase in the production cost of single crystal silicon.

Boron oxide, the formula is B2O3. It is a hard, white and glassy crystals which is one of the oxides of boron and produced from high purity Boron acid. Boron oxide can be dissolved in acid, ethanol, hot water, and slightly dissolved in cold water. It is much slower absorb in water than the boron acid if exposed to the air and much slower soluble in water than boron acid. Boron oxide is stable under ordinary conditions of use and storage. If moisture is present, boron oxide can be corrosive to iron. Boron oxide is widely used in the Specialty Glasses, Refractories industry, Ceramics, Glazes and enamels, Chemical reactions and Metallurgy industry, etc.
