Borax is a soft and light colorless translucent crystal or white crystalline powder. Chemically, it's sodium tetrborate with 10 water molecules. Borax is odorless and salty. Soluble in water, glycerine, slightly soluble in alcohol, aqueous solution is slightly alkaline. Borax can be weathered slowly in the air and melt into a colorless glassy substance.
Application scope
· Borax has many USES, we are familiar with such as using borax as a disinfectant, preservative, water softening agent, eye wash, stuffing for washing powder and soap, glaze and glass raw materials for ceramics, etc.
· In the metallurgical industry, borax is used for calcining, welding and metal testing and is a good flux; When welding metals, borax is used to clean their surfaces.
· It is also used to make optical glass, enamel and enamel. In the glass, it can enhance the ultraviolet transmittance, improve the transparency and heat resistance of the glass. In enamel products, it can make the glaze is not easy to fall off and give it luster; It is also widely used in the fields of special optical glass, glass fiber, binder of jewelry, printing and dyeing, washing (silk and wool, etc.), refining of gold, cosmetics, pesticides, fertilizers, borax soap, preservatives, antifreeze and disinfectant for medical use.
Borax is the basic raw material for making boron compounds. Almost all borides can be made from borax. They are important and widely used in metallurgy, iron and steel, machinery, military industry, cutting tools, papermaking, vacuum tube, chemical industry and textile sectors. Boranes, a compound of boron, can also act as high-energy rocket fuel.
