Use
Sodium tetrafluoroborate is a versatile chemical with diverse applications:
Metal smelting and refining: Used as an oxide suppressant and flux in the refining process of non-ferrous metals like aluminum, magnesium, titanium, enhancing metal purity and reducing production costs.
Coatings and corrosion-resistant materials: Enhances adhesion and corrosion resistance in coatings, improving weather resistance and gloss. It is also utilized in the creation of corrosion-resistant and fireproof materials.
Textile printing and dyeing: Commonly employed as a textile printing and dyeing auxiliary for waterproofing and oil resistance and also used in producing cellulose films for packaging and protecting food.
Electroplating and surface treatment: Serves in preparing chemicals for metal electroplating and surface treatment like galvanizing, copper plating, and silver plating.
Other fields: Sodium fluoroborate finds use in producing efficient catalysts, high-energy-density batteries, polymer electrolytes, and high-temperature lubricants.
