Abstract

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.
