Product Description

 Pharmaceutical Chemical Pharmaceutical Intermediate Raw Powder CAS10043-35-3 Boric Acid

Boric acid, also called hydrogen borate, boracic acid, orth  acid and acidum boricum, is a weak, monobasic Lewis acid of boron, which is often used as an antiseptic, insecticide, flame retardant, neutron absorber, or precursor to other chemical compounds. It has the chemical formula H3BO3 (sometimes written B(OH)3), and exists in the form of colorless crystals or a white powder that dissolves in water. When occurring as a mineral, it is called sassolite.
application
1. Boric acid is mainly used in glass products, especially in heat-resistant and chemical resistant glass products. Boron carbide made of boric acid can be used as an abrasive. In addition, it can be used in enamel, ceramic glaze, inorganic pigment, fertilizer and metallurgical production.
2. Used as a pH regulator, disinfectant, antibacterial preservative, etc. Used in the preparation of borate, borate, optical glass, paint, pigment, boric acid soap, leather finishing agent, printing and dyeing auxiliary and medicine Disinfectant, etc.
3. Used in capacitor manufacturing and electronic component industry Chemicalbook, high-purity analytical reagents, medicinal disinfection and anti-corrosion, and preparation of chemical solutions for processing and processing of exposed photosensitive materials.
4. Used in glass, enamel, ceramics, medicine, metallurgy, leather, dyes, pesticides, fertilizers, textiles and other industries
5. Used as a chromatographic analysis reagent and also used in the preparation of buffers
