Boron Oxide Is The Important Raw Materials Of Heat Resistant Galss
Boron oxide (B2O3), Formula Weight is 69.63.B2O3 can reduce the coefficient of expansion of glass, provide thermal stability and chemical stability of glass, increase the refractive index of glass, improve the gloss of glass and improve the mechanical properties of glass. B2O3 can reduce the viscosity of glass at high temperature and improve the viscosity of the glass at low temperature, so the glass with higher content of B2O3 has a wider forming temperature range. B2O3 also acts as a flux to accelerate the dissolution and clarification of the glass.
