A low-temperature fast-fired lightweight ceramic heat insulation plate and a preparation method thereof. The preparation method comprises: performing ball milling and powder spraying on a raw material containing foamable ceramic waste slag to prepare foamable powder, the foamable ceramic waste slag accounting for 80-100 wt % of the weight of the raw material; uniformly mixing 100 weight portions of the foamable powder with 3-15 weight portions of granular powder of a low-melting-point organic matter to obtain mixed powder materials; pressing the mixed powder materials under 10-20 MPa to prepare a ceramic green body; and firing the ceramic green body at a temperature of 1100-1170 C. to prepare the lightweight energy-saving ceramic heat insulation plate.

The present disclosure relates to a process for making ceramic tiles characterized by the addition to the ceramic raw materials of an aqueous slurry comprising a swellable clay of the smectite family, a binder and a water-soluble salt of a monovalent cation.

A process for making tiles comprising: i) mixing the ceramic raw materials; ii) dry-grinding the ceramic raw materials or wet-grinding the ceramic raw materials and spray drying the ceramic slip obtained from the wet-grinding; iii) forming green tiles by pressing the powdery grinded ceramic raw materials obtained from step ii); said process being characterized by the addition to the ceramic raw materials, before step iii), of from 0.01 to 5.0% by weight, based on the weight of the ceramic raw materials (dry matter), of a composition comprising a polymer obtained by polymerization in the presence of a sugar or a degraded polysaccharide.
