Description

Boron Sodium Oxide (B3Nao5) is an inorganic chemical compound with the formula Na₂B₄O₇, commonly known as sodium borate. This versatile material serves as a fundamental source of boron, a critical element valued for its glass-forming, fluxing, and fire-retardant properties in industrial processes. It is essential for manufacturers in the glass, ceramics, metallurgy, and agricultural sectors seeking a reliable and consistent boron supply.

Application

• Glass and Ceramics Manufacturing: Acts as a primary fluxing agent to lower melting temperatures and improve the thermal and chemical durability of borosilicate glass, fiberglass, and ceramic glazes.
• Metallurgy and Welding: Used as a flux in metal refining and welding rods to remove oxides and impurities, ensuring cleaner metal surfaces and stronger joints.
• Agriculture: Serves as a micronutrient fertilizer and a component in formulations to correct boron deficiency in soils, promoting healthy plant growth and crop yield.
• Flame Retardants: Incorporated into polymers, textiles, and wood treatments to impart fire-resistant properties by promoting char formation.
• Detergents and Cleaners: Functions as a water softener, buffer, and bleach stabilizer in laundry and cleaning product formulations.
• Adhesives and Sealants: Used as a cross-linking agent and preservative to enhance the performance and shelf-life of various adhesive products.
• Laboratory and Chemical Synthesis: Employed as a buffering agent, catalyst, or reagent in various chemical processes and analytical applications.
