Boron trioxide, boron oxide is also known as "boric anhydride". The chemical formula B2O3 is soluble in hot water, but only slightly hot in cold water. Forms orthoboric acid in water. Volatile metaboric acid is formed in the hot water vapor. In the molten state, it can dissolve a variety of metal oxides to obtain colored boron glass. Alkali metals, magnesium and aluminum can reduce it to elemental boron. To obtain high-purity boron oxide, high-purity boric acid must be prepared first. The preparation methods of high-purity boric acid mainly include recrystallization, ion exchange, complexation, esterification-hydrolysis, membrane separation, electrochemical, and adsorption. Law etc.

Application of boron trioxide powder:

Boron oxide can be widely used as a flux in the decomposition of silicate, a dopant for semiconductor materials, an acid catalyst in organic synthesis, a refractory additive for paint, and a raw material for preparing elemental boron and a variety of borides, etc., high purity oxidation Boron (≥99.999%) is the liquid sealing agent in the manufacture of III~V compound semiconductors (such as gallium arsenide, gallium phosphide, indium arsenide). With the rapid development of the LED industry in recent years, the output of its substrate material gallium arsenide has increased, and the demand for high-purity boron oxide has also increased. 

Storage conditions:
Boron trioxide powder should be sealed and stored in a dry and cool environment. It should not be exposed to the air for a long time, to prevent agglomeration due to moisture, affecting the dispersion performance and use effect, and should avoid heavy pressure, do not contact with oxidant, and transport according to ordinary goods.
