Boric Acid
Boric Acid Manufacturer & Bulk Supplier for Industrial and Agricultural Applications -
High-Purity Boric Acid with Controlled Chemical Composition & Precision Mesh Sizes
Boric Acid (H3BO3), CAS No. 10043-35-3, is a primary inorganic boron source available in refined powder and granular forms. Efficient chemical processing depends on far more than a headline purity percentage. Downstream production requires tight control over trace impurities including sulfate, chloride, iron, heavy metals, water-insoluble matter, and particle size distribution.
Zouping Jinxing Chemical manufactures and supplies technical-grade, agricultural-grade, reagent-grade, and pharmaceutical-compliant Boric Acid tailored to strict B2B operating environments.
Rather than enforcing a rigid single-spec model, we assist procurement teams in matching raw material parameters with their exact batch formulations, storage capabilities, and regional regulatory standards.
Annual Production Capacity: 50,000+ MT | Exporting to 40+ Countries | ISO 9001 & REACH Compliant

Glass and Fiberglass Manufacturing
Boric Acid introduces B2O3 into borosilicate glass and continuous filament fiberglass melts, optimizing thermal shock resistance and chemical durability. Strict control of iron (Fe) is maintained to prevent unwanted coloration in clear glass.
Agriculture & Micronutrient Formulations
Functions as a concentrated, plant-available boron source. Used in dry fertilizer blending, liquid foliar applications, and soil amendment production.
Ceramic Glazes and Enamels
Acts as a powerful fluxing agent, reducing firing temperatures and enhancing glaze thermal expansion coefficients.
Metallurgical Processing & Fluxes
Utilized in high-temperature metal treatment, soldering fluxes, and specialized metal alloy refining.
Chemical Manufacturing & Synthesis
Serves as a reactive boron donor in synthesized chemical intermediates, flame-retardant chemistry, and corrosion inhibitors.
