Yttrium (III) Oxide Pieces/Pellets

99.5% - 99.999% pure

Yttrium oxide is white in color with a melting point of 2,410°C.

It has a density of 5.01 g/cc, and vapor pressure of 10^-4 Torr at ~2,000°C.

Applications:  Yttrium oxide is used to make phosphors, which provide the color red in televisions, and yttrium iron garnets are an essential element of microwave filters.

Yttrium oxide is evaporated under a vacuum for the fabrication of semiconductors and passive components.
