Zirconium oxide pre-fired body suitable for dental use
Provided is a zirconia pre-sintered body having suitable color tone, light transmittance, and strength. The present invention pertains to a zirconia pre-sintered body having a laminated structure of at least three layers containing zirconia and a stabilizer capable of suppressing phase change of zirconia, the laminated structure being provided with at least two layers in which the content of the stabilizer relative to the total molar content of zirconia and stabilizer is different from each other, the layered structure is provided with at least two layers in which the content of the stabilizer is substantially the same with respect to the total molar content of zirconia and stabilizer, all the layers in which the content of the stabilizer is substantially the same contain a coloring component, and the compositions of the coloring components in the layers are different from each other.
本发明提供具有适合的色调、透光性和强度的氧化锆预烧体。本发明涉及氧化锆预烧体，其具备含有氧化锆和能够抑制氧化锆相变的稳定剂的至少3层的层叠结构，前述层叠结构具备至少2层稳定剂相对于氧化锆和稳定剂的总摩尔的含量互不相同的层，前述层叠结构具备至少2层稳定剂相对于氧化锆和稳定剂的总摩尔的含量大致相同的层，稳定剂的含量大致相同的所有层包含着色成分，且该层中的着色成分的组成互不相同。
