 Properties :

Borax(Borax Decahydrate), also known as crude borax, is soft and light colorless crystalline substance. Borax(Borax Decahydrate) has many uses we are familiar with, such as disinfectant, preservative, water softener, wash water, soap additives, ceramic glaze and glass raw materials. Borax also have an important role in industrial production. Borax Physicochemical properties:

Colorless translucent crystals or white crystalline powder. Odorless, taste salty. Soluble in water and glycerine easily, slightly soluble in alcohol. Weakly alkaline aqueous solution. Borax in the air can be slowly weathering. Borax are sterilization, oral harmful to people.
