    摘要: The invention comprises a multilayer high-strength, high-toughness, flaw-tolerant oxide ceramic composite having a metal phosphate later, a first yttria stabilized zirconia layer, a yttria stabilized zirconia-alumina layer and a second yttria stabilized zirconia layer; and a method for producing the same. The metal phosphate are selected from the group consisting of monazites, xenotimes, calcium phosphate, aluminum phosphate, zirconium phosphate and substituted zirconnium phosphate wherein Zr.sup.4+ is partially replaced by divalent metal ions. The ceramic composition of the invention may be further strengthened by the incorporation of selected particulates, whiskers or fibers, or mixture of the same, into the yttria stabilized zirconia layers, the yttria stabilized zirconia-alumina layers and the metal phosphate layers. A multilayer ceramic of the invention comprising a YPO.sub.4 layer, a first yttria stabilized zirconia layer, a 30 vol % yttria stabilized zirconia-70 vol % alumina layer and a second yttria stabilized zirconia layer was found to have a 4-point flexural strength of 358, 392 MPa and an apparent work-of-fracture in the range of 8.2, 10 kJ/m.sup.2.

The ceramic materials are useful in the production of capacitors or modules having high performance such as high dielectric constants and low TCC values with low cost. The ceramic powder also can mix with a glass component of low melting temperature to form a low temperature co-fired capacitor.
