(JA) ジルコニア焼結体及びその製造方法
Abstract
(EN)
Provided is at least one of: a zirconia sintered body which can be used in a wider variety of applications compared with the conventional ceramic bonded bodies each containing transparent zirconia; and a method for producing the zirconia sintered body. A zirconia sintered body provided with a transparent zirconia part and an opaque zirconia part, the zirconia sintered body being characterized by having bi-axial bending strength of 300 MPa or more.
(FR)
L'invention concerne au moins un élément parmi : un corps fritté en zircone qui peut être utilisé dans une plus grande diversité d'applications par comparaison avec les corps liés en céramique classiques contenant chacun de la zircone transparente ; et un procédé de production du corps fritté en zircone. L'invention concerne également un corps fritté en zircone pourvu d'une partie en zircone transparente et d'une partie en zircone opaque, le corps fritté en zircone étant caractérisé en ce qu'il présente une résistance à la flexion bi-axiale supérieure ou égale à 300 MPa.
