Furthermore, if it oxidizes at high temperature and forms a thick oxide film, the emissivity will be around 0.8cm. arise. In addition, the painting method often has the problem of deterioration of the paint film, and if heat-resistant stainless steel is used as the base material, there is a problem in the adhesion of the paint film, and there is also the disadvantage of increased costs.

A specimen degreased with acetone was immersed in an alkali metal hydroxide solution, in this case a 5-chloride NaOH alcohol solution, at room temperature, an alkali gold nugget compound, in this case a Na compound, was attached to the surface of the specimen, and the specimen was pulled out and dried. . Next, this test piece was placed in an electric furnace in an oxygen atmosphere, that is, an air atmosphere, and subjected to a heating oxidation treatment at 600° C. for 30 minutes. This treatment produced a brown film. Measured values of emissivity of this film at room temperature and 6008C (respectively εR-T+
