Borax:sodium tetraborate decahydrate;

Molecular formula: Na2B4O7.10H2O, scientific name sodium tetraborate. Borax is a basic boride, the main mineral raw material for the extraction of boron and boride, and the precursor of many other borides, from which thousands of boron inorganic compounds and organic compounds can be derived. In the metallurgical industry, borax is used for calcination, welding and metal testing, and is a good flux. Borax can be used as a filler for washing powder and soap. It is also a raw material for the manufacture of optical glass, enamel and enamel. It can also be used to make artificial gems and welds. Medicine, etc. After refining and refining, it can be used as a heat-clearing and detoxifying agent. It is cool, sweet and salty, and can cure sore throat, gums, mouth sores, and eyelid disorders. Borax is also commonly used as a metal rust remover. In agriculture, borax can act as a boron fertilizer. Boron compound borane can also act on high energy rocket fuel.

With the development of modern industry, borax and its derived borides have played an important role in modern science and technology. They have been on the big stage of the material industry from the original raw material role, and their applications have been related to light industrial textiles and household chemicals, glass enamel ceramics, metallurgical industry, pharmaceutical industry, electromechanical industry, electronics industry, nuclear industry and high-tech. Technology, agriculture and many other fields have been widely used in various sectors of the national economy.
