Abstract

Ceramic eutectics grown from the melt have great structural advantages compared to conventional ceramics and also properties that make them suitable for applications as electronic and optical materials. The preparation of ordered lamellar eutectics of ZrO2(c)[BOND]CaZrO3 is described and the macroscopic and engineering characteristics of the material reported. The Figure shows an optical micrograph of a transverse section obtained in the transmission illumination mode.
