Russian Boric Acid (H₃BO₃) with 99.9% Purity - Flame-Retardant and Bacteriostatic for Industrial Applications

Boric Acid is a refined inorganic fine chemical product from Hongjian Chemical, renowned for its unique layered crystal structure, mild acidity, and flame-retardant and bacteriostatic properties. It plays a critical role in high-end manufacturing and livelihood security.

The company employs the advanced "Borax-Sulfuric Acid Acidification Process," achieving 99.9% high purity through the reaction: Na₂B₄O₇*10H₂O + H₂SO₄ → 4H₃BO₃ + Na₂SO₃ + 5H₂O.
