Zirconium oxide material and a sintered molded body produced from the material. The zirconium oxide is present in the tetragonal phase in an amount of 70 to 99.9 vol.-%. The tetragonal phase is chemically stabilized with rare-earth oxides. The sintered moldings can be used, e.g., in the medical field as implants or as dental prostheses.

Zirconia-based monophase and multiphase materials

A composite material having a first phase includes an aluminum oxide proportion of at least 65% by volume and a second phase comprising a zirconium proportion of 10 to 35% by volume. The zirconium is present as zirconium oxide. The aluminum oxide is a ceramic matrix and the zirconium oxide is dispersed therein. From 90 to 99% of the zirconium oxide is present in the tetragonal phase. A chemical stabilizer for stabilizing the tetragonal phase of the zirconium oxide is also present. The total content of chemical stabilizer is &#x3c;0.2 mol % relative to the zirconium oxide content.

Ceramic composite material consisting of aluminium oxide and zirconium oxide as main constitutents

A ceramic composite material and a method for producing same. The ceramic composite material has a ceramic matrix comprising zirconium oxide and at least one secondary phase dispersed therein. The matrix is composed of zirconium oxide as at least 51 vol.-% of composite material, and the secondary phase is in a proportion of 1 to 49 vol.-% of composite material, wherein 90 to 99% of the zirconium oxide is present in the tetragonal phase based on the total zirconium oxide portion. The tetragonal phase of the zirconium oxide is stabilized by at least one member selected from the group consisting of chemical stabilization and mechanical stabilization. The ceramic composite is damage-tolerant.

Zirconium oxide-based composite material

A composite material consisting of aluminium oxide as a ceramic matrix and zirconium oxide dispersed therein. A method for the production thereof, components containing the composite and methods of using the same are also provided.
