Sodium tetraborate decahydrate CAS 1303-96-4, commonly written as Na2B4O7 · 10H2O, is a very important boron containing mineral and compound. Usually a white powder containing colorless crystals, easily soluble in water. Borax has a wide range of uses, including as a cleaning agent, cosmetics, insecticide, as well as for preparing buffer solutions and preparing other boron compounds. Commercial borax is often partially weathered. Borax has high toxicity and is often banned as a food additive in many countries around the world. If the human body ingests too much boron, it can cause cumulative poisoning of multiple organs.

Application

Borax has a wide range of uses, as a filler for laundry detergent and soap, as well as a raw material for manufacturing optical glass, enamel, and enamel. It can also be used to manufacture artificial gemstones, welding flux, and so on. After extraction and refinement, it can be used as a heat clearing and detoxifying medicine, with a cool nature and a sweet and salty taste. It can treat symptoms such as sore throat, toothache, aphthous ulcers, and eye growth disorders. Borax melts into a colorless glassy substance used in the manufacture of special optical glass. It can dissolve some metal oxides in a molten state and exhibit characteristic colors according to different metals. For example, when dissolving cobalt oxide, it turns dark blue due to the formation of Co (BO2) 2, Cu (BO2) 2 turns blue, Cr (BO2) 3 turns green, and MnO2 · 2B2ChemicalbookO3 turns purple. Therefore, in analytical chemistry, borax bead experiments can be used to identify metal ions. This property is also applied to the enamel and glass industries, using above glaze or coloring; Also used for artificial gemstones. When welding metal, borax is used as a welding flux to remove oxides from the metal surface. Borax aqueous solution exhibits alkalinity and can be used as a filler for soap and laundry detergent. Used as a preservative in medicine. Traditional Chinese medicine is used as a detoxifying agent. In the chemical industry, it is the raw material for manufacturing a series of boron compounds. Borax solution is used as plant fertilizer. The mixture of boric acid and magnesium sulfate, namely boron magnesium fertilizer, can be obtained by reacting the leftover materials (magnesium hydroxide and mother liquor of borax) of borax production with sulfuric acid. Borax is also a raw material for producing boric acid.
