Borax, also known as crude borax, is both soft and light colorless crystalline material. Borax has many uses, such aswe are familiar with disinfectant, preservative preservatives, water softener, wash water, soap additives, ceramic glaze and glass raw materials in industrial production also has an important role in borax.

(1) Borax can be used as jewelry adhesive, printing and dyeing, washing (silk, wool, etc.), gold refining, cosmetics, pesticides, fertilizers, borax soap, medical preservatives, antifreeze, disinfectants, etc.
(2) In the metallurgical industry, borax is used for calcination, welding and metal testing, and is also a good flux; When welding metal, borax is used to purify the surface of the metal.
(3) Raw materials for ceramic glazes and glass. In the glass, the transmission rate of ultraviolet light can be improved, and the transparency and heat resistance of the glass can be improved. In enamel products, it can make the enamel not easy to fall off and make it shiny; Also widely used in special optical glass, glass fiber.
(4) Borax is the basic raw material for the production of boron-containing compounds, and almost all boron compounds can be made from borax.
