3. Application
(1). Borax has many USES, such as the familiar use of borax as disinfectant, preservative, soft water agent, eye washing water, fillers for laundry powder and soap, ceramic glaze and glass raw materials.· in metallurgical industry, borax is used for calcining, welding and metal test, and it is also a good flux; Borax is used to purify metal surfaces when welding metals.

(2). It is also the raw material for optical glass, enamel and enamel. In glass, the transmission rate of ultraviolet ray can be enhanced, and the transparency and heat resistance of glass can be improved. In enamel products, it can make the enamel not easy to fall off and make it shiny; It is also widely used in special optical glass, glass fiber, jewelry adhesives, printing and dyeing, washing (silk and wool, etc.), gold refining, cosmetics, pesticides, fertilizers, borax soap, preservatives, antifreeze and disinfectant for medical use.

(3). Borax is the basic raw material for the production of boron-containing compounds. Almost all boron compounds can be made by borax. They have important and extensive USES in metallurgy, iron and steel, machinery,  industry, cutting tools, papermaking, electronic tubes, chemical and textile sectors. Boron compounds borane can also act as high-energy rocket fuel.
