ABSTRACT:
Aqueous ceramic slurry compositions comprising a critical mixture of lithium silicate, sodium silicate, zirconia powder, glass frit and a magnetic filler, within predetermined amounts, and process of coating substrates therewith by spray or brush methods, and rapidly curing at low temperatures, up to about 500.degree. F. and as low as below about 375.degree. F. This provides a solid, protective, electromagnetic ceramic layer which is resistant to high humidity degradation or blistering after exposure to temperatures of about 1000.degree. F., such as 0.4 mach hot gas.
