PURPOSE:To provide a composite ceramic with strong thermal shock resistance and a method for preparation thereof. CONSTITUTION:The title composite ceramic consists of a compsn. wherein the thermal expansion coefficient is gradually changed from one side to another side and a method for preparation of the composite ceramic wherein ceramic particles each with different specific gravity and thermal expansion coefficient are mixed at a specified ratio and the mixture is dispersed by a wet process and then, sedimentation of the dispersed mixture is performed and after dehydration and drying are performed, it is calcined, is provided. |
