  • Patent number: 10202307
    Abstract: The present application discloses a sintered ceramic material having high fracture toughness and bending strength, which is obtained from an yttria-stabilized Zirconia powder, the powder composition for obtaining said material, sintered ceramic pieces and manufacturing process thereof. One of the solutions of the present invention discloses a sintered ceramic material which is obtained from an yttria-stabilized zirconia powder, comprising between 1.8 and 2.1 mol % yttria, wherein the sintered ceramic material has a percentage of tetragonal phase greater than 90% at room temperature, a grain size between 0.1 to 0.25 ?m, the bending strength is between 1150-2100 MPa, and simultaneously a toughness greater than 10 MPa·m1/2. This material may be applied in different sintered ceramic pieces, including pieces for the automotive sector, for diverse machinery, ornamental applications such as timepieces or pieces for biomedical applications, among others.
