Barium sulfite

Barium sulfite (CAS 7787-39-5), also referenced as barium sulphite, is an inorganic barium salt used industrially as a reducing and preservative agent. It functions primarily to control oxidative degradation and microbial activity in process streams and treatment baths.

In water treatment, it acts as an oxygen scavenger and pH buffer, helping to protect process equipment from corrosive degradation. Textile and leather processing operations use it in dyebath preparation and tanning liquors.

Controlled reduction chemistry improves dye uptake and process consistency within these specialized industrial environments. Pulp and paper manufacturers incorporate it into bleaching and pulping stages to moderate oxidative conditions.

This application helps extend the working life of process chemicals during large-scale manufacturing cycles. It also serves preservation functions in industrial formulations where sulfite-based biocidal activity is required.

This activity is essential to inhibit microbial growth in aqueous systems and maintain product stability over time. Barium sulfite is supplied as a white crystalline powder or fine granules for easy handling.

Technical grade is the standard commercial form for industrial applications across various sectors. Buyers should confirm purity specifications and barium content with suppliers before finalizing procurement orders.

These specifications often vary by production source and intended end use, requiring careful review of technical data sheets. Proper documentation ensures the material meets the specific needs of the application.
