Gasket for high-temperature joint and method of fabricating the same

摘要

Provided is a gasket capable of maintaining a high sealing property under a high temperature, in which a gasket basic substance and coverture are not sublimated or decomposed when the gasket is used under a high temperature above 500° C. The gasket for a high-temperature joint includes a gasket basic substance formed by filling a heat-resistant filler mainly composed of diatomaceous earth into gaps of a meshed metallic reinforcing member, and coverture made of a heat-resistant antifriction material mainly composed of a mixture of boron nitride and polytetrafluoroethylene resin for covering a surface of the gasket basic substance.
