Borax Pentahydrate & Borax Decahydrate | Industrial Chemical Trading by ChemTech

Introduction to Borax Pentahydrate and Decahydrate

Borax, also known as Sodium Tetraborate or Sodium Borate, is one of the most important inorganic boron compounds, commonly available in two forms:
Borax Pentahydrate (Na₂B₄O₇·5H₂O) and Borax Decahydrate (Na₂B₄O₇·10H₂O).

These compounds are widely used in various industries due to their alkaline, antifungal, water-softening, and fluxing properties.
Borax plays a vital role in glassmaking, detergents, metallurgy, agriculture, and textile production.

ChemTech, as a professional chemical trading and distribution company, supplies both Borax Pentahydrate and Borax Decahydrate from reliable global manufacturers.
We ensure high purity, consistent quality, and industrial-grade packaging suitable for a broad range of applications.

Industrial Applications of Borax

  1. Glass and Ceramics Industry

Borax is a key raw material in the production of borosilicate glass, glazes, and ceramics.
It helps reduce the melting point, enhances thermal resistance, and improves transparency and durability.

  1. Detergent and Cleaning Industry

In the manufacture of laundry powders, soaps, and household cleaners, borax functions as a pH buffer and water softener, improving cleaning efficiency.

  1. Metallurgy and Welding

Used as a fluxing agent, borax assists in soldering, brazing, and metal refining by removing oxides and preventing metal oxidation.

  1. Agriculture

Borax acts as an essential source of boron in micronutrient fertilizers, promoting healthy plant growth, flowering, and fruit formation.

  1. Textile and Paper Industries

Employed in bleaching, disinfecting, and color-fixing processes, as well as in paper pulp production to enhance brightness and quality.

  1. Wood Preservation and Fire Retardants

Borax is used as an antifungal, insecticidal, and fire-retardant additive for wood, panels, and cellulose-based materials.
