Sodium metaborate

Sodium metaborate (CAS 7775-19-1 ), also referenced commercially as NaBO2, is an inorganic boron-containing salt used across industrial processes for pH regulation, corrosion inhibition, and biocidal activity. It functions as an alkaline buffer and preservative in formulations where controlled boron release and stable pH are both required. In water treatment, it controls pH and inhibits corrosion in recirculating systems. This chemical reduces metal degradation in pipelines and cooling towers. Textile and leather processing operations use it as an alkaline scouring and cleaning agent to remove grease and organic contaminants from surfaces. In agriculture, it serves as a boron micronutrient source in soil treatment programs targeting boron-deficient crops. Paper manufacturing applies it in pulping and bleaching stages for consistent process chemistry. Its buffering capacity supports consistent process chemistry and helps protect equipment surfaces. Sodium metaborate is supplied as an anhydrous powder or as hydrated crystalline forms, most commonly the tetrahydrate. Technical grade is the standard offering for industrial applications across water treatment, textile, and paper sectors. Buyers should confirm anhydrous versus hydrated form when specifying for their needs. Boron content and solubility behavior differ between grades, making specification critical. This versatile chemical remains a staple for industrial manufacturers requiring reliable alkaline buffering and protection. Contact us for supply of Sodium metaborate Request Quote
