Detailed Description

Scandium Oxide also called Scandia, is suitable for the high index component of UV, AR and bandpass coatings due to its high index value, transparency, and layer hardness make high damage thresholds have been reported for combinations with silicon dioxide or magnesium fluoride for use in AR. Application Scandium Oxide is used in electronic industries , laser and superconducting materials ; its also used as additive for alloy and all kinds of cathode coating , vapor deposition materials for semiconductor coating ; used to make solid state laser for variable wavelength , television electron gun and metal halide lamp.
