摘要

Disclosed is to provide a material which can withstand rapid increase in temperature to 1600°C or more and exhibits little change in properties even in a high-speed combustion gas stream. Specifically disclosed is a SiC fiber-bonded ceramic coated with SiC, which is characterized by being produced by coating the surface of a SiC fiber-bonded ceramic with use of a coating layer including mainly SiC, wherein the SiC fiber-bonded ceramic includes inorganic fibers having a sintered SiC structure, each of which contains 0.01 to 1 wt% of oxygen (O) and at least one or more metal atoms of metal atoms in Groups 2A, 3A, and 3B and a 1-100 nm interfacial layer containing carbon (C) as a main component formed between the fibers.
