Used as a flux in metallurgy and ceramic production to lower melting temperatures and improve processing efficiency. Employed in the synthesis of specialty glasses and enamel coatings due to its ability to enhance durability and thermal resistance. Also utilized in electroplating baths to improve metal deposition quality and in the preparation of other fluorosilicate compounds for industrial applications. Shows use in some battery-related research as a source of fluoride ions and lithium in experimental electrolyte formulations. Additionally, applied in water treatment and corrosion inhibition in certain industrial systems.
