Abstract
A ceramic sheet comprising 5 to 50 wt. % (absolute dry weight) of a cation-modified pulp having a degree of substitution of cationic group of 0.02 to 0.04 and beaten to freeness of 200 to 100 ml C.S.F. and 50 to 95 wt. % of fine inorganic particles dispersed uniformly in and supported by said cation-modified pulp. This ceramic sheet can be easily prepared from an aqueous suspension of the cation-modified pulp and the fine inorganic particles by using a paper-making treatment.
