Insulation tile and multi-layered insulating member

Abstract

This invention provides heat-resistant ceramic tiles that exhibit high thermal insulation and durability even in processing temperature ranges exceeding 2300°C, and multilayer thermal insulation materials incorporating these properties. As a solution, the heat-resistant ceramic tile comprises a substrate A composed of porous carbon, and a coating layer formed on at least one surface of the substrate A, comprising a high-melting-point metal carbide, wherein the relative density of the coating layer is 95% or higher. The multilayer thermal insulation material comprises a substrate B composed of a shaped thermal insulation material comprising carbon fibers, and a heat-resistant ceramic tile disposed on the surface of the substrate B, wherein the heat-resistant ceramic tile is disposed on the surface of the substrate B with the coating layer facing the external atmosphere.
