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.
