ABSTRACT:
The invention provides a novel composition useful as a heat-resistant coating material on the surface of a metal or ceramic article or as an adhesive agent for bonding metal articles, ceramic articles, or articles of a metal and a ceramic. The adhesive strength of the composition is so strong that no peeling takes place even after many repeated cycles of rapid heating and cooling. The composition comprises a refractory powder of an inorganic oxide, such as alumina and silica; a powdery inorganic compound having cation-exchangeability and a layered structure, such as mica; and an alkali metal silicate or aluminate as a binder. The maximum particle diameter of the powdery inorganic compound having a layered structure is important and relative to the average particle diameter of the refractory powder.
