摘要：
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.
