BassTech International offers a complete line of Lithium Salts, including Lithium Fluoride. Lithium Fluoride is a water insoluble Lithium source used in oxygen-sensitive applications, such as metal production. It is most widely used as a flux in the production of ceramics, such as enamels, glasses and glazes. Similarly it is also used in brazing and welding fluxes and molten salt chemistry in metallurgy. It is also used in the soldering progress for glass lining as a cosolvent.
