Description

BaF2 is relatively hard but is highly sensitive to thermal shock. For its transmission range is 0.2 Î&frac*4;m - *1 Î&frac*4;m, the material is used for optical windows, lenses and prisms in UV-IR. Besides it can also be used as substrate for some applications. BaF2 is less resistant to attack by water than CaF2. Pronounced water attack occurs at **0 &deg;C, but in a dry environment the material can be used to **0 &deg;C. BaF2 is grown by modified Bridgman technique. Maximum available size: **0 mm Dia x *0 mm Thk. Besides, BaF2 is usually used as scintillator for gamma detection. It is the fastest scintillating crystals up to now.
