Sodium metaborate tetrahydrate

Sodium metaborate tetrahydrate (CAS 10555-76-7) is a hydrated boron-sodium salt used industrially as a pH buffer and corrosion inhibitor.

Where is Sodium metaborate tetrahydrate used?

• Water treatment: buffering agent that maintains stable alkalinity
• Cooling water and industrial circulation systems: corrosion inhibitor
• Textile, leather and paper processing: bath pH regulator during dyeing, tanning and pulp treatment
• Cement and concrete formulations: component for controlled setting chemistry
• Building materials: borate-based preservation
• Agriculture: boron micronutrient source in soil amendment and foliar products
• It releases borate ions in solution for alkalinity control and metal surface protection.

Good to know: Controlled solubility is a key formulation requirement for agricultural uses.

Commercial specifications

• Packaging from 25 kg bags to bulk quantities
