Abstract: Provided is a high-light transmittance zirconia sintered body, prepared by processing and forming a material for the high-light transmittance zirconia sintered body, and then performing high-temperature sintering in the atmosphere under normal pressure. The material for a high-light transmittance zirconia sintered body is prepared from zirconia powder and α-aluminum oxide as raw materials, wherein the molar percentage of yttrium oxide in the zirconia powder is 4-6%. The high-light transmittance zirconia sintered body can be used for preparing a fixed dental prosthesis. The zirconia sintered body has a grain size of 0.1-0.7 μm, and due to the dispersion and toughening by aluminum oxide, the zirconia sintered body has a higher strength and toughness. Pores in the zirconia powder can be eliminated by adding aluminum oxide. The zirconia sintered body has a higher light transmittance, and the prepared dentures are good in texture, good in jade-like appearance, and closer to the human teeth.

Abstract: A black zirconia sintered body is obtained by processing and forming a powder for the black zirconia sintered body, and then sintering the same at a high temperature and normal pressure in the atmosphere. The powder for the black zirconia sintered body is prepared by a hydrothermal synthesis method using a soluble zirconium salt, a soluble yttrium salt and a color former as raw materials, wherein the molar ratio of the soluble zirconium salt, the soluble yttrium salt and the color former is 90-95:1-5:1-9. The black zirconia sintered body can be used in ceramic processes.
