Film Properties
Evap. Temp.: 2100 ºC
Film Growth: crystalline with low
packing density
Film Hardness: Hard
Common uses: Used
for aluminum mirror protection coatings, in UV laser antireflection coatings and high
reflectors. Specimen support for electron diffration.
Comments: High temperature dielectric. Adhesion is good on glass, other oxide
materials, and some plastics. Less background oxygen is needed to obtain low
absorbing films. |
