Lithium Fluoride

Product Overview
Lithium fluoride (LiF) is an alkali metal halide with an extremely high melting point (848°C) and boiling point (1681°C). It is typically found as a white crystalline solid or powder at room temperature. Lithium fluoride is soluble in acids, slightly soluble in water, and insoluble in ethanol and acetone. It is widely used in industries such as metallurgy, ceramics, optics, and energy, and plays a significant role in high-temperature batteries, optical materials, and nuclear energy applications due to its unique physical properties.

Product Features
