Beschreibung
Zusammenfassung:	Provided is at least one of a sintered body having both high dynamic and static strength, a method for manufacturing this sintered body, a powder, and a pre-sintered body. A sintered body of zirconia has a stabilizing element, which contains at least one rare earth element other than yttrium, the average crystal grain diameter being 0.05-0.75 µm, and having a region which undergoes plastic deformation. L'invention concerne au moins élément parmi un corps fritté ayant une haute résistance dynamique et statique, un procédé de fabrication de ce corps fritté, une poudre et un corps pré-fritté. Un corps fritté de zircone comporte un élément de stabilisation, qui contient au moins un élément des terres rares autre que l'yttrium, le diamètre moyen des grains cristallins étant de 0,05 à 0,75 µm, et ayant une région qui subit une déformation plastique. 動的強度及び静的強度のいずれの強度も高い焼結体、その焼結体の製造方法、粉末、及び、仮焼体の少なくともいずれかを提供する。安定化元素を含有し、該安定化元素がイットリウム以外の希土類元素を少なくとも１種含有し、平均結晶粒径が０．０５μｍ以上０．７５μｍ以下であり、かつ、塑性変形する領域を有するジルコニアの焼結体である。
