Product Description
Attributes  --------------------------------------------------------------------------------------------------------------------  Chemical Names: Yttrium aluminum oxide  Molecular Formula: Al5O12Y3  Molecular Weight: 593.618043 g/mol Application  -------------------------------------------------------------------------------------------------------------------- Because, among the 300nm wavelength index close to 1.9, yttrium oxide may be used in stacks with silicon dioxide (n = 1.48) for UV laser applications. In the visible region, it is sufficient that the index of intermediate value,. For three layer broadband AR coatings on glass Environmental protection money and aluminum mirror was revealed in the near UV through the IR far. Yttrium shows no residual radiation strip less than 18 Pm m, and therefore no reflection loss to large angles of incidence seen with oxides of silicon and aluminum oxide products.Description  --------------------------------------------------------------------------------------------------------------------Yttrium oxide is thermodynamically stable compound. In the oxide group is resistant to many molten reactive metals such as titanium and uranium. In its industrial application as a pure ceramic, yttrium oxide is still a relatively new material. Especially its high temperature resistance - up to about 2200°C - and excellent resistance to alkaline substance with high affinity to oxygen, this material is used in many special applications.Yttrium oxide, Y2O3, is a medium-index, low-absorption material usable for coatings in the near-UV (300 nm) to IR (12 µm) regions. Hard, dense layers are deposited by electron-beam evaporation or sputtering. Typical applications are protection of aluminum and silver mirror coatings, intermediate layer in wide band visible AR coatings and for XeCl (308 nm) laser AR and dielectric mirror designs. Yttria can be used in combination with silicon dioxide layers to form a high index-contrast structure and also with higher index materials such as titania
