1.Specification:1)Borax, also known as crude borax, is both soft and light colorless crystalline material. Borax has many uses, such as we 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.
2)Colorless translucent crystals or white crystalline powder. Odorless, taste salty. Proportion of 1.73. 380 °C when the loss of all the crystal water. Soluble in water, glycerol, slightly soluble in alcohol. Weakly alkaline solution. Borax in the air can slowly weathering. Melting into a colorless glassy

2.Use:1)Mainly used in glass and enamel industries. In the glass, can enhance UV transmission rate and improve the transparency and heat resistance of glass. Products in the enamel, the enamel can not easily fall off and to make it shine.
2)In the special optical glass, borax Glass fiber, non-ferrous metal welding agent, jewelry adhesives, printing and dyeing, washing (silk and wool, etc.), refined gold, cosmetics, pesticides, fertilizers, borax soap, preservatives, antifreeze and medical use of disinfectants, etc. there are a wide range of applications. Preparation of boron-containing compounds, borax is the basic raw materials, almost all come with borides can be obtained by the borax.
3)In recent years, also used for cancer treatment. In animal medicine, borax for chicken laryngotracheitis, infectious impetigo goats, pig mycoplasma pneumonia, chronic mucus bovine endometritis treatment, feed additives as much attention.
4)It is a component of many detergents, cosmetics, and enamel glazes. It is also used to make buffer solutions in biochemistry, as a fire retardant, as an anti-fungal compound for fiberglass, as an insecticide, as a flux in metallurgy, a texturing agent in cooking, and as a precursor for other boron compounds.
