Packing: 50KGs Iron Drum
Stability: Slightly hygroscopic
Application: 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.
Synonyms: Scandium oxide;oxygen(-2) anion; scandium(+3) cation
