(57) [Summary] [Constitution] According to the present invention, a base material obtained by coating a non-oxide ceramic such as silicon carbide on a carbon material, and further, two of aluminum, silicon, zirconium and magnesium are used. What is formed is a film of oxide of more than one kind of metal, and a method for producing the same. The heat resistant structural material according to the present invention provides a lightweight structural material that can be used in an oxidizing atmosphere and at a high temperature of 1500 ° C. or higher. |
