1. Used as pH regulator, disinfectant, bacteriostatic preservative, etc
2. Boric acid can be used in capacitor manufacturing and electronic component industry, high purity analytical reagents,
disinfection and anticorrosion, and preparation of exposed sensitive materials washing processing liquid.
3. Used in glass, enamel, ceramics, metallurgy, leather, dye, fertilizer, textile and other industries
4. Used as chromatographic analysis reagent, also used for buffer preparation
A large number of used in glass (optical glass, acid-resistant glass, heat-resistant glass, insulating materials with glass fiber) industry, can improve the heat resistance, transparency of glass products, improve mechanical strength, shorten the melting time.
