The melting points of SiC, Al, and Si cannot be lowered sufficiently, and a dense protective film cannot be formed on the surface of the refractory-supporting metal article, and the effect of preventing oxidative damage cannot be sufficiently obtained. If the blending ratio exceeds 5%, the melting points of SiC, Al, and Si become too low, and the coating material is absorbed by the surrounding refractory material, so that the surface oxidation preventing effect of the refractory material cannot be sufficiently obtained. For this reason, it is preferable to add 0.5 to 5% of powdery or liquid metal salts such as Ca, Na and K. Liquid Ca, Na, K is powdered Ca, Na, K mixed with a solvent to be in a fluid state.

For example, when the cross-sectional area is 50 mm 2 , it is about 0.5 mm and the cross-sectional area is 100 m.
In the case of m 2 , a thickness of about 0.8 mm is suitable, and the thickness of the coating material to be applied can be easily adjusted by adjusting the viscosity by adjusting the proportion of the solvent.

Water, alcohol, and thinner contained in the coating material evaporate or volatilize, and the pulp fibers, plastics, and liquid synthetic resin are burned off by heating to reduce the thickness of the coating material. A void is formed between the refractory and the refractory, and the thermal expansion margin of the refractory holding metal is compensated for by the void. Further, since SiC, Al, and Si form a dense film on the surface of the refractory-holding metal article, oxidative damage of the refractory-holding metal article in a high temperature region can be prevented.
