Barium
Fluoride is used for optical windows, lenses and prisms. The
transmission range is 0.2¦Ìm - 11¦Ìm. Barium fluoride is grown
by vacuum Stockbarger technique. Polishing is quicker than
calcium fluoride using diamond pastes but is less easy to
obtain free of sleeks. Barium fluoride is less resistant to
attack by water than Calcium Fluoride. Pronounced water attack
occurs at 500 ¡ãC, but the material can be used to 800 ¡ãC in
a dry environment. The material is relatively hard but is
highly sensitive to thermal shock.
