Yttrium Oxide

Yttrium oxide is white powder, insoluble in water and alkali, soluble in acids. Density: 5.01 g / cm3, melting point 2,425 °C, boiling point 4,300 °C.

Yttrium oxide mainly used for the production of microwave magnetic materials and an important material for military use (single crystal; yttrium iron garnet, yttrium aluminum garnet and other composite oxide), also used as an optical glass, ceramic materials additives, big-screen TV with a high-brightness phosphor and other CRT coatings. Also used in the manufacture of film capacitors and special refractories, as well as high-pressure mercury lamp, a laser, a magnetic bubble storage element and other materials. Added sintering yttrium oxide can effectively reduce the grain size of tungsten alloy.
