Boric acid
Application of boric acid:
1. boric acid in glass industry: Optical glass, Acid-resisting glass,Heat resistant glass, Glass fibre, improve the heat-resisting and transparency of glass, and increase the mechanical strength, and shorten the dissolve melting time;
2. ceramic Industry: the main part of glaze, strengthen the enamel product luster and fastness;
3. boric acid metallurgy Industry: One key additive on Ferro-Boron alloy and Boron steel, and strengthen their hardness and ductility;
4. boric acid medicine: Desinfectant and Preservatives; Astringent and insecticide;
5. Binder: For fluting paper;
6. Others: Retardant material, Nuke industry, Leather, Rust-proof, Paint, Electroplate etc.
