  FUCTION AND APPLICATION

  
  

  Borax is an inorganic compound, generally written as Na2B4O7·10H2O, with a molecular weight of 381.37. Borax is a very important boron-containing mineral and boron compound. It is usually a white powder containing colorless crystals and is easily soluble in water. Borax is the sodium salt of boric acid, the general name of sodium tetraborate, and it is a mineral containing boron. According to the amount of crystal water, there are three types of borax decahydrate, borax pentahydrate and anhydrous borax.
  In addition to heat resistance, water resistance and acid resistance, borax also has a strong dissolving ability. The borax becomes white and swells after heating, and becomes a transparent glass ball. The metal oxide can be dissolved in it and the original color of the metal can be restored. This is the famous borax ball reaction.
  use
  Borax can be used as a filler for washing powder and soap. It is also a raw material for manufacturing optical glass, enamel and enamel. It can also be used for manufacturing artificial gems and solder. After being refined and refined, it can be used as a heat-clearing and detoxifying medicine, which is cool in nature, sweet and salty in taste, and can cure sore throat, malnutrition, aphthous ulcers, and ecchymosis.
