Product Code : EM-LiF-5N-Cu
Lithium Fluoride (LiF) is a relatively rare evaporation material used in some ultra-high vacuum systems and electron microscopy applications. LiF has a low vapor pressure and a high rate of decomposition, which makes it useful for preventing chemical deposition of other materials on substrates and insulation components. LiF has a melting point of 848 °C and a boiling point of 1456 °C. It is a hygroscopic material and should be stored between -70°C and +70°C. When evaporating LiF, it is important to use an even heat distribution to prevent localized temperatures that could lead to the appearance of a ridge on the sample surfaces.
