  • Body made of a ceramic material
    Patent number: 10752553
    Abstract: A body made of a ceramic material based on zirconia, the body having a surface region extending from the surface of the body to a predetermined depth and a core region integrally formed with the surface region. The ceramic material in the surface region includes a crystalline phase A formed by zirconia in tetragonal phase. The ceramic material in the surface region further includes a crystalline phase B, the crystal structure of which including apart from zirconium and oxygen at least one further component X in a periodic arrangement, the crystalline phase B having a lower theoretical density than crystalline phase A.
