Ceramic bodies made from metal oxide powders have been used for some time in the preparation of dental products due to their good biocompatibility and stability under loads. Transport of ceramic bodies is usually done by, for example, cutting the body or sintering with a sharp knife. Smart bodies are made by compacting metal oxide powder by cold isostatic pressing or uniaxial pressing. After processing, the body must be sintered W to obtain the final properties. The sintered body is prepared by hot isostatic pressing, from which the metal oxide powder is compacted and sintered simultaneously.
Cambuddy has been particularly important, but oxidation errors have been considered because of its greater mechanical strength than cambuddy. Tetragonal system oxidation errors have unusual mechanical strength due to the phase transition mechanism of sample transport, which is triggered when the crack expands into the material, causing the rupture to stop. However, tetragonal oxidation errors are now found to be opaque, thus limiting applications where the seed material needs higher semi-transparency, such as dental applications. Semitransparent cubic system oxidation errors are known, but they have relatively low mechanical strength. Therefore, there has always been a need for ceramic main bodies with both high strength and semi-transparency.
A semi-transparent tetragonal crystal system has been developed. Thus, in one respect, the present invention provides a translucent oxide missintered body useful in dental products. In one embodiment, a translucent oxidized missintered body consisting of primary particles and at least 99% full density is provided. A kind of oxygenated sinter which can be used to prepare semi-transparent oxidized sinter and dental products is provided. In one embodiment, an oxidation faulting body is provided consisting of primary particles and having a density of at least 50% of the full density.
