Borax Powder

Description

Borax Decahydrate Powder is a technical-grade disodium tetraborate decahydrate (Na₂B₄O₇·10H₂O) refined from tincal ore through a controlled production process.

It is a white crystalline alkaline salt with excellent buffering and flow properties, making it suitable for applications across glass, agriculture, detergents, ceramics, metallurgy, water treatment, adhesives, cosmetics, and fire-retardant formulations.

Designed for reliable industrial processing, Borax Decahydrate Powder has a specific gravity of 1.73 g/cm³, a bulk density of approximately 0.882 g/cm³, and a molecular weight of 381.37 g/mol. It exhibits stable alkaline pH in aqueous solutions and increased solubility at higher temperatures, supporting controlled dissolution and consistent process performance.

The product offers a consistent chemical composition containing 36.47–38.50% B₂O₃, 11.33–11.96% boron, and 16.24–17.14% Na₂O, with controlled levels of sulphate, chloride, iron, and heavy metals. Combined with a controlled particle size distribution, these properties help ensure consistent handling, quality, and performance in industrial applications.
