Ceramic fiber refractory moldable compositions

摘要

A moldable refractory composition consisting essentially of defined quantities of liquid vehicle; ceramic fiber; inorganic binder derived from a colloidal dispersion; and organic binder which is a high molecular weight polar organic polymer; the liquid vehicle being a solvent for the organic binder and a non-solvent for the ceramic fiber; the composition having defined solid content, defined density, defined viscosity and defined modulus of rupture. Also described are a method of manufacture of the composition, and a method of forming a refractory moldable shape.
