white crystalline powder or colorless microstrip pearl luster phosphor or hexagonal triclinic crystal. Tasteless, slightly sour and bitter. The melting point was about 171 °c. Soluble in water, alcohol, glycerol, ethers and essential oils, aqueous solution is weakly acidic. The solubility of boric acid in water increases with the increase of temperature, and can volatilize 0. Imol/L water solution with water vapor at pH 5.1. 19 can be dissolved in 18mL cold water, 4mL boiling water, 18mL cold alcohol, 6mL boiling alcohol or 4mL glycerol. Contact with the skin has a smooth feeling, no change in the open air. When heated to 100~105 ºC, it loses one minute of water and forms metaboric acid. When heated at 104~160 ºC for a long time, it changes to pyroboric acid, and when heated at higher temperature, it forms anhydrous, 300 C when the formation of boric anhydride (B2 03).
