ZIRCONIA PRE-SINTERED BODY HAVING GOOD MACHINABILITY
The present invention provides a zirconia pre-sintered body having excellent machinability and having a low probability of pillar fracture or chipping during milling. A method of production of such a zirconia pre-sintered body is also provided. The present invention relates to a zirconia pre-sintered body comprising zirconia, and a stabilizer capable of reducing a phase transformation of zirconia, the content of the stabilizer being 3 to 8 mol % relative to the total mole of the zirconia and the stabilizer, at least a part of the stabilizer being not dissolved in zirconia as a solid solution, and the zirconia pre-sintered body having a Vickers hardness of 65 to 135 HV 5/30 as measured in compliance with JIS Z 2244:2009.
