An inorganic 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, comprises (1) a refractory powder of an inorganic oxide, such as alumina or silica; (2) a powdery inorganic compound having cation- exchangeability and a layered structure, such as mica; and (3) an alkali metal silicate or aluminate as a binder. The maximum particle diameter of the powdery inorganic compound (2) should be smaller than the average particle diameter of the refractory powder (1). Preferably the binder is present in an amount in the range 15-50 wt.% of the total of the other two constituents. |
