Molecular formula: Na2B4O7.10H2O Molecular weight: 381.37 CAS Number: 1303-96-4
Translucent colorless crystals or crystalline white powder; odorless, salty taste; anhydrous borax is called anhydrous borax when heated to 350-400℃ and lose all crystal water. (Na2B4O7), density 1.72g/cm3; easily soluble in water, soluble in glycerin, insoluble in alcohol. Its aqueous solution is weakly alkaline and appears colorless glass when melted. It has a bactericidal effect and is harmful to the human body when taken orally. In terms of chemical composition, it is sodium tetraborate containing 10 water molecules. Its crystals are plate-shaped or column-shaped, and the crystals gather together to form clusters, granular, porous soil blocks, etc., and the color is white with gray or yellow, blue, green, etc., with a glassy luster. Borax is a soft and light colorless translucent crystal or white crystalline powder. In terms of chemical composition, it is sodium tetraborate containing 10 water molecules. Borax is odorless and salty. It is easily soluble in water and glycerin, slightly soluble in alcohol, and the aqueous solution is weakly alkaline. Borax can be slowly weathered in the air, and becomes a colorless glassy substance when it is melted. [ Scope of Application ] · Borax has many uses, such as the use of borax as a disinfectant, fresh-keeping preservative, water softener, eye wash, filler for washing powder and soap, ceramic glaze and glass raw materials. · In the metallurgical industry, borax is used for forging, welding and metal testing, and it is also a good flux; when welding metals, people use borax to purify the metal surface. · It is also a raw material for manufacturing optical glass, enamel and enamel. In glass, it can enhance the transmittance of ultraviolet rays, improve the transparency and heat resistance of glass; in enamel products, it can make the enamel not easy to fall off and make it shiny; in special optical glass, glass fiber, jewelry binder, Printing and dyeing, washing (silk and wool, etc.), gold refining, cosmetics, pesticides, fertilizers, borax soap, preservatives, antifreeze and medical disinfectants are also widely used. · Borax is the basic raw material for preparing boron-containing compounds. Almost all boron-containing compounds can be prepared from borax. They are widely used in metallurgy, iron and steel, machinery, military industry, knives, papermaking, electronic tubes, chemicals and textiles and other sectors; boron compound borane can also be used as high-energy rocket fuel.
