Boric acid is converted to metaboric acid  (HBO2) on heating to 100-130°C and with further heating up into water-free boron trioxide. Boric acid, similar to boron trioxide, is the starting material for the production of other boron compounds (e.g. boron nitride, boron carbide, etc.). It is further used for the production of borosilicate glasses, as well as addition enamels and in the refractory industry. It is used as a sinter aid for ramming compounds in induction furnaces. Furthermore boric acid is added to magnesite masses in order to avoid hydration. Also with the help of boric acid crucible glazes are produced.
