Abstract
An expansion graphite sheet of high thermal resistance includes an expansion graphite as a main component, and inorganic thermal resistance particles made of at least one selected from the group consisting of aluminum boride (AlBand/or AlB), silicon boride (SiB), zinc boric acid (2ZnO.3BO.3.5HO) and phosphorous boride (PB). An exhaust gasket made of the expansion graphite sheet, in addition to the expansion graphite sheet, can exhibit high thermal (oxidization) resistance under a high temperature of 600–700° C.
