It‘s mainly used for manufacturing dielectric ceramics (MLCC) and laser crystals (YAG), also used for optical glass, ceramic material additive y-zr, high luminance phosphors and other picture tube coating. It is also used in making film capacitors and special refractories, as well as magnetic bubble materials such as high pressure mercury lamps, lasers and storage components. The addition of yttrium oxide during sintering can effectively reduce the grain size of tungsten alloy.
