EspañolProduct overview
Boric acid, an inorganic compound with the chemical formula H3BO3, is a white crystalline powder with a slippery feel and no smell.
It is used in large quantities in the glass industry to improve the heat resistance and transparency of glass products, increase mechanical strength and shorten melting time, and is also used as an antiseptic and disinfectant.
Applications
1. Used in the production of optical glass, acid-resistant glass, organic boron glass and other advanced glass and glass fibres, it can improve the heat resistance and transparency of glass, increase the mechanical strength and shorten the melting time.
2. In the ceramics industry, boric acid is a very good flux and network formers, boron is also an important component of lead-free glaze, while improving the speed of colouring, used in the production of glaze, can reduce the thermal expansion of glaze, reduce the.
