Abstract
Refractory furnace wall coating composition comprising from about 45 to about 65% by weight of silicon carbide, from about 10 to about 15% by weight of stabilized zirconium oxide or bentonite, from about 5 to about 10% by weight of silicon dioxide, from about 3 to about 5% by weight of hydrolyzate of poly(ethyl silicate), from about 10 to about 20% by weight of sodium silicate or aluminum phosphate, the balance being water, is disclosed.
Claims2
A refractory furnace wall coating composition comprising from about 45 to about 65% by weight of silicon carbide, from about 10 to about 15% by weight of a compound selected from the group consisting of stabilized zirconium oxide, bentonite, and a mixture thereof, from about 5 to about 10% by weight of silicon dioxide, from about 3 to about 5% by weight of a hydrolyzate of a poly (ethyl silicate), said hydrolyzate having the formula ##STR2## from about 10 to about 20% by weight of a compound selected from the group consisting of sodium silicate, aluminum phosphate, and a mixture thereof, the balance being water, the percent being based on the weight of the composition.
