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 across water treatment, construction, and agricultural applications.

It releases borate ions in solution, making it effective for alkalinity control and metal surface protection in process systems. In water treatment, it functions as a buffering agent to maintain stable alkalinity.

The compound helps inhibit corrosion in cooling water and industrial circulation systems. Textile, leather, and paper processing operations use it to regulate bath pH during dyeing, tanning, and pulp treatment.

Consistent alkalinity directly affects product quality in these industrial processes. In building and construction, it serves as a component in cement and concrete formulations requiring controlled setting chemistry.

It is also utilized for borate-based preservation in various building materials. Agricultural applications include its use as a boron micronutrient source in soil amendment and foliar treatment products.

Controlled solubility is a key formulation requirement for these agricultural uses. The product is supplied as a white crystalline powder or granular solid for easy handling and dissolution.

It is available in technical grade for industrial applications including water treatment and construction. Packaging typically ranges from 25 kg bags to bulk quantities depending on application volume.
