Fields of application

Industry

Application Notes

Borosilicate glass

Significantly reduces the coefficient of thermal expansion, enhancing heat resistance and impact strength for laboratory glassware, cookware, ampoule vials, and display glass.

Ceramic glazes

Lowering the melting temperature of the glaze results in a smoother, harder, and more wear-resistant glaze surface, enhancing both gloss and chemical stability.

Flame retardant

Forms a glass-like coating upon combustion, providing thermal insulation and oxygen barrier properties, suitable for plastics, rubber, coatings, and textiles.

Metallurgical industry

Used as a fluxing agent to remove oxides from metal surfaces, thereby enhancing welding quality and smelting efficiency.
