Main Applications
Glass & Ceramics: Acts as a flux to lower melting temperature, improve transparency and thermal stability of glass; enhances glaze hardness and gloss in ceramics.
Metallurgy & Welding: Used as a soldering flux to remove metal oxides, improving the strength of brazing joints.
Detergents & Cleaning: Serves as a water softener and pH buffer to boost detergency, especially for delicate fabrics like silk and wool.
Refractory Materials: Stabilizes refractory products and forms a rigid skeleton structure.
Chemical Industry: Raw material for manufacturing other boron compounds (e.g., boric acid, borates).
Laboratory Reagent: Prepares buffer solutions for biochemical analysis.
