Product Name: Orthoboric acid
CAS: 10043-35-3;11113-50-1
Molecular Formula: H3BO3
Molecular Weight: 61.833
Synonyms: Boron acid;Boric Acid

Boric acid CAS 10043-35-3/11113-50-1 exists in 99.6% white flakes (1~3mm/3~5mm) and 99.5% white crystalline powder. It is a high purity boric acid. Boric acid is actually boric oxide Hydrate. Specific gravity of 1.43 5(15℃). Boric acid’s solubility in water increases with temperature rise, and volatile with the steam; And its solubility in the inorganic acid is smaller than that in water.
