ABSTRACT:
A high emissivity coating for coating the interior of a furnace to direct thermal energy toward a load in the furnace wherein the furnace operates above 1100.degree. C. The high emissivity coating includes a high emissivity agent and a binder agent. The preferred high emissivity agent is cerium oxide which defines a high emissivity factor from approximately 1000.degree. C. to above 2000.degree. C. The binder suspension agent is formulated to define the consistency and drying characteristics of paint such that the coating can be applied in a manner similar to the manner in which paint is applied. Moreover, the binder/suspension agent withstands the final use temperature.
