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. |
