Application Of Boric Acid
1. Ceramic industry: B2O3 is a good flux and network forming agent for ceramics and enamel glazes.
2.Glass industry: can improve the heat resistance and transparency of glass products, and increase mechanical strength.
3.Antibacterial industry: mixed with borax to adjust the pH value of the buffer solution, used as a crosslinking agent to emulsify paraffin and can be used as an antibacterial agent;
4.Additive industry: can be used as an additive for rust inhibitors, lubricants, thermal oxidation stabilizers, brake oil, water treatment agents, etc.
5.Agriculture: producing boron containing trace fertilizers for insecticides and herbicides, mixing boric acid and borax into aqueous solutions, and spraying them as foliar fertilizers, etc.
