ABSTRACT:
A lime-free silicon carbide based refractory containing about 87 wt.% silicon carbide sized -10 mesh, about 5 wt.% alumina sized -325 mesh, about 3 wt.% silica sub-micron size, and about 5 wt.% alkaliphosphate modified alumino-silicate binder. This material finds particular applicability in the construction of cast shapes and troughs for non-ferrous metal production and as a refractory lining for boiler tubes.
