Boric acid is actually a hydrate of boron oxide（B2O3·3H2O）,It is white powder crystal or triclinic axis surface flake luster crystal with greasy handle and no odor. proportion1.435（15oC）。Soluble in water, alcohol, glycerin, ethers and essential oils, the aqueous solution is weakly acidic. The solubility of boric acid in water increases with the increase of temperature and volatilizes with water vapor; the solubility of boric acid in inorganic acid is smaller than that in water. Heat to70～100℃boric acid is formed by dehydration，150～160℃Pyroboric acid is formed at 300 ℃ and boric anhydride is formed at 300 ℃（B2O3）
