1. For Glass & Fiberglass Production: Boric acid (H₃BO₃, CAS 10043-35-3) is a key raw material in borosilicate glass, fiberglass and glass fiber production, improving thermal shock resistance, chemical durability and optical clarity of glass products.
2. For Flame Retardant & Wood Treatment: Boric acid acts as an effective flame retardant for cellulose insulation, wood, textiles and paper, reducing flame spread and supporting fire-safety treatment in construction and furniture applications.
3. For Agricultural Micronutrient Fertilizer: As a boron micronutrient source, boric acid corrects boron deficiency in crops, supporting flowering, fruit set and yield in field crops, orchards and greenhouse cultivation when applied in fertilizers or foliar sprays.
4. For Metallurgy & Electroplating: Boric acid serves as a flux and buffering agent in metallurgical processes and electroplating baths, stabilizing pH and improving deposit quality in nickel and other plating operations.
5. For Chemical Intermediates & Borates: Boric acid is a fundamental intermediate for producing borates, boron esters, borax derivatives and specialty boron chemicals used across glass, ceramic, detergent and fine chemical industries.
6. Consistent Quality For Global Industry: Supplied as high-purity white crystalline powder or granules with stable assay and consistent quality, boric acid gives glass, agricultural, metallurgical and chemical manufacturers a dependable boron source with flexible packaging and stable supply.
