Borax is mainly used in the glass and enamel industries. In glass, it enhances the transmittance of ultraviolet light and improves the transparency and heat resistance of glass. In the enamel product, the enamel can be easily peeled off to make it shiny. In special optical glass,

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

Borax is the basic raw material for the preparation of boron-containing compounds, and almost all of the boride-containing compounds can be obtained by borax. They have important and wide-ranging uses in the metals, steel, machinery, military, tool, paper, tube, chemical and textile sectors.

In medicine, borax is used for the treatment of skin mucosa, antiseptic, fluorosis, athlete's foot, pulpitis, fungal vaginitis, cervical erosion, hemorrhoids, hemorrhoids, external ear canal eczema, herpes virus skin disease, epilepsy. For the treatment of tumors. In animal medicine, borax is used in the treatment of chicken laryngotracheitis, goat infectious pustulosis, Mycoplasma pneumoniae, and chronic mucinous endometritis. It has also attracted people's attention as a feed additive.

It is used as herbicide for non-cultivation area, and it is mixed with sodium chlorate to reduce the flammability of sodium chlorate.

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 in foreign countries. However, there are abundant borax mines in China. Therefore, boron is not a rare element in China, but a high-yield element. Industrially, borax is also used as a solid lubricant for metal wire drawing and the like. In the welding repair of refrigerators, electric freezers, air conditioners and other refrigeration equipment, it is often used as (inactive) flux to purify metal surfaces. Remove oxides from the metal surface; add a certain proportion of sodium chloride to the borax. Compounds such as sodium fluoride and potassium chloride can be used as active fluxes for welding between copper pipes and steel pipes, steel pipes and steel pipes in refrigeration equipment.
