Ceramics with a glaze applied to the surface of ceramic blank, the bending strength of which ceramic blank is,Mpa or higher or the firing shrinkage rate is 7% or higher and the porosity is 7.5% or higher.

Ceramics, ceramic blank, manufacturing method thereof, sanitary earthenware and manufacturing method thereof

A method for preparing high strength and high thermal shock-resistant china for ceramic whiteware which comprises the steps of molding a china-forming raw material which mainly comprises a natural ore material capable of forming corundum through firing or a material obtained by calcining the natural ore material to form corundum, a natural ore material capable of forming mullite through firing or a material obtained by calcining the natural ore material to form mullite, a clayey material and a flux such as feldspar, nepheline or dolomite; and then firing the molded china-forming raw material. The method permits the production of cheaper china for ceramic whiteware having high strength and excellent thermal shock resistance as compared with those prepared by the conventional techniques.
