Application
Mainly used for the production of microwave magnetic materials and 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.
