摘要：

Different samples of zirconia-doped alumina and spinel ceramics have been obtained and characterized. Their mechanical and dielectric properties at high frequencies have been measured. The dependence of these properties on the concentrations of the different zirconia phases is discussed. From the results obtained it is concluded that the dispersion of tetragonal zirconia particles in the ceramics causes strength and toughness to be improved without almost any degradation in dielectric properties, while monoclinic zirconia increases the dielectric loss.
