Packing: 1 kg or 5 kg per package, 50 kg iron drum, provide small package: 100g, 500g, and other small packages.
Used: Used as additive for various ceramics, optical glass, phosphors, laser materials and refractory materials. Ultrafine yttrium oxide powder can be made into polycrystalline ceramics with excellent transparency. This kind of ceramics has high linear transmittance in the infrared and far infrared region, and has high paramagnetism and fluorescence which are not possessed by ordinary ceramics It can be used in window and fairing, radome, microwave substrate, infrared lens, infrared generator tube and other high temperature windows of infrared guided missile. In addition, the ultra-fine yttria powder can also be dispersed in the alloy to obtain super heat-resistant alloy; the stabilized zirconia powder can be sintered into stable zirconia ceramics with high strength and toughness, which can be used for cutting tools and mechanical parts.
