PROBLEM TO BE SOLVED: To provide a coating composition for a high temperature refractory ceramic substrate.SOLUTION: There is disclosed a refractory coating consisting of nonstabilized zirconia, silica, and zircon and/or mullite as an option. The nonstabilized zirconia, silica, and optional zircon and/or mullite is applied to be calcined as a slurry to a ceramic substrate such as a silicon carbide. When applied to the ceramic substrate, the refractory coating maintains good edge definition and good color in case of being exposed to a temperature higher than 1,100°C. |
