Suscepter and process for production thereof.

摘要

A suscepter, which is composed substantially of a vitreous carbon derived from polycarbodiimide resin; and a process for producing a suscepter, which comprises molding a polycarbodiimide resin or a composition composed mainly of a polycarbodiimide resin, into a shape of a suscepter and then carbonizing the molded material in vacuum or an inert gas atmosphere. Said suscepter is free from the problems of the prior art, which has no pores on the surface and generates no impurity and which causes no cracking when used at high temperatures
