Description
Lithium Fluoride (LiF) has the lowest refractive index of all common
infrared materials. It possesses the highest UV transmission of any
material, being able to transmit significantly into the VUV region
at the hydrogen Lyman-alpha line (121nm).
Lithium fluoride can be applied in rechargeable Li batteries, in
radiation dosimeter for personnel monitoring as well as radiation
research, as an optical material, as a heat sink material, to
produce ceramics, and to dissolve fluid fuel for molten salt
reactors. |
