Bulk Properties
Melting Point: 2410
ºC
Density: 5.01 gm/cc

Film Properties
Evap. Temp.: 2400 ºC
Film Growth: Amorphous
Film Hardness: Hard
Common uses: Multilayer
coatings. UV Coatings. Environmental protection of silver and aluminum
mirrors. Antireflection coatings.
Comments: Under low energy deposition conditions (i.e. resistive) or
high pressure conditions, films may exhibit absorption bands at 2.9mm and 6.9mm due to water
adsorption. Preconditioning of material before evaporation at a reduced power for
several minutes is recommended.
