ABSTRACT:
The invention provides a novel composition useful as a heat-resistant coating material for a metal or ceramic article surface. Also, the novel composition is useful 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 times of repeated cycles of rapid heating and quenching. The composition comprises a metal powder, such as iron, copper and silver; a powdery inorganic compound having cation-exchangeability and a layered structure, such as mica; and a binder of an alkali metal silicate or aluminate. The maximum particle diameter of the layered inorganic compound having a layered structure is important and relative to the average particle diameter of the metal powder.
