Chemische Eigenschaften
white powder(s) or sintered tablets and pieces of 99.9% purity; bcc; readily absorbs atmospheric CO2; enthalpy of fusion 105.00 kJ/mol; used in crucible form for experimental, proprietary melting, also sintered pieces used as evaporation material for hard film dielectric coating and thin film capacitors, and as 99.999%, 99.99%, 99.9% pure sputtering target for preparing hard films, dielectric coatings, and thin film capacitor [CER91] [MER06] [CRC10]
Physikalische Eigenschaften
Yttrium oxide is a medium-refractiveindex, low-absorption material
used for optical coating in the
near-UV (300 nm) to IR (12 μm)
regions and hence used to
protect Al and Ag mirrors. Used
for crucibles containing molten
lithium.
Verwenden
Yttrium oxide is an excellent mineralizing agent for spinel formation. Yttrium oxide is used as a common starting material for both materials science as well as inorganic compounds. Provides easy application of uniform, thin, protective high temperature Yttrium Oxide coatings. Yttrium Oxide is used to produce Yttrium-Iron-Garnets, which are very effective microwave filters. Low purity of Yttrium Oxide are widely applied in electronic ceramics. Yttrium Oxide is also used to make Yttrium-Iron-Garnets, which are very effective microwave filters.
Allgemeine Beschreibung
Yttrium oxide is an excellent mineralizing agent for spinel formation. It has a high melting point(2450
oC), chemical stability, low coefficient of thermal expansion, high transparency for both visible (70%) and infrared (60%) light, low cut off energy of photons.
Sicherheitsprofil
A poison by intraperitoneal route. See also
