The chemical formula which best characterizes the Yttrium - oxide Y2O3, white with a yellow powder, insoluble in water and alkali, soluble in acid. Mainly used for manufacture of microwave with magnetic materials and military industry with important material (single crystal; zhe yttrium iron garnet, zhe yttrium aluminum garnet and other composite oxide), also used as optical glass, ceramic material additives, a giant TV screen, with high brightness tube fluorescent powder and other coatings, etc.
Yttrium oxide - mainly used for manufacture of microwave with magnetic materials and military industry with important material (single crystal; zhe Yttrium iron garnet, zhe Yttrium aluminum garnet and other composite oxide), also used as optical glass, ceramic material additives, a giant TV screen, with high brightness tube fluorescent powder and other coatings. Also used in the manufacture of film capacitors and special refractories, and high pressure mercury lamp, laser, storage element such as bubble material. Sinter adding yttrium oxide can effectively reduce the grain size of tungsten alloy.
