Abstract
A heat insulating coating material is provided by admixing an alkali metal silicate binder and water with aggregates comprising silica-containing inorganic refractory fibers, silica-containing porous refractory materials and silica-containing powdery refractory materials. The alkali metal silicate binder can be replaced by a phosphate binder, depending upon the nature of an atmosphere, and finely divided metals can be incorporated into the aggregates.
