Borax, generally written as Na2B4O7·10H2O, is a very important boron-containing mineral and boron compound. It is usually a white powder containing colorless crystals, easily soluble in water. Borax has a wide range of uses. It can be used as a cleaning agent, cosmetics, and insecticide. It can also be used to prepare buffer solutions and prepare other boron compounds.

Main application

Borax is the basic raw material for preparing boron-containing compounds. Almost all boron-containing compounds can be prepared from borax. They have important and wide-ranging applications in sectors such as metallurgy, steel, machinery, military industry, knives, papermaking, electronic tubes, chemicals and textiles.

Glass and enamel industry

In glass, it can enhance the transmittance of ultraviolet rays, improve the transparency and heat resistance of glass. In enamel products, the glaze can not easily fall off and make it shiny. In special optical glass,

Glass fiber, non-ferrous metal welding agent, jewelry binder, printing and dyeing, washing (silk and wool, etc.), gold refining, cosmetics, pesticides, fertilizers, borax soap, preservatives, antifreeze and medical disinfectants, etc. There are also a wide range of applications.

Industrial field

In industry, borax is the most important industrial boron mineral. Borax is the most important compound of boron. Boron is often listed as a rare element abroad, but there are abundant borax mines in my country. Therefore, boron is not a rare element in my country, but a high-yield element. In industry, borax is also used as a solid lubricant for metal wire drawing. It is often used as (inactive) flux in the welding and maintenance of refrigeration equipment such as refrigerators, electric freezers, and air conditioners to purify metal surfaces. Remove oxides on the metal surface; add a certain proportion of sodium chloride to borax. Compounds such as sodium fluoride and potassium chloride can be used as active fluxes for welding copper pipes and steel pipes, steel pipes and steel pipes in refrigeration equipment.

Other application

Borax is widely used in industrial and agricultural production. For example, it can be used as filler and surface activity enhancement (cross-linking) in washing powder and soap; it is also widely used in glass fiber, welding non-ferrous metals, bonding jewellery, cosmetic antiseptic, pesticide, fertilizer, antifreeze and medical disinfectant etc. It is used as a herbicide in agriculture, and for killing weeds in non-cultivated areas.
