A preparation method comprises: preparing a green body using green body powder; applying an overglaze on the surface of the green body; ink-jet printing a pattern on the surface of green body; applying a protective glaze on the surface of the green body; applying an anti-counterfeiting material on the surface of the green body; firing the green body, titanite and high-refractive-index oxide being wetted and wrapped by a molten liquid produced by melting a low-temperature glaze powder in a firing environment, and sunken into the protective glaze without generating opacification; and then polishing to obtain a ceramic plate having an anti-counterfeiting visual effect. The anti-counterfeiting visual effect is a visual effect in which a high-intensity refraction effect is achieved when the sight line direction is consistent with the path of reflected light, but no refraction effect is achieved when the sight line direction deviates from the path.

The present invention relates to a ceramic slate with a colored jade effect and a preparation method comprising: pressing and forming raw materials containing a ceramic base material and colored glass fragments to obtain a ceramic green body; drying and firing the ceramic green body to give a ceramic slate with colored jade effect particles dispersed on the surface of the green body; wherein, the colored glass fragments account for 3 wt % to 5 wt % of the ceramic base material. Since colored glass waste instead of frits and pigments is used to prepare the ceramic slate with the colored jade effect, the ceramic slate does not have the phenomenon of pigment dispersion after high-temperature firing, and the surface of the fired ceramic slate shows a shape of micro-protrusion, so that the polished tile surface is smoother and free from pits, resulting in a better tile surface effect.

Disclosed are a low-shrinkage, high-strength, and large ceramic plate and a manufacturing method thereof. The method comprises the following steps: (1) preparing a ceramic raw material powder; (2) subjecting an acicular wollastonite to surface coating with a silane coupling agent and to pre-dispersion with a fumed silica to obtain a pre-treated acicular wollastonite; and (3) thoroughly mixing the ceramic raw material powder and the pre-treated acicular wollastonite and granulating the resulting mixture, the amount of the pre-treated acicular wollastonite added being 10 wt% to 30 wt% of the ceramic raw material powder, and subjecting the resulting granules to dry pressing and sintering to obtain the low-shrinkage, high-strength, and large ceramic plate. The acicular wollastonite is incorporated into the manufacturing of the large ceramic plate to take full advantage of the reinforcing effect and low sintering shrinkage characteristics of the acicular wollastonite. The invention reduces sintering shrinkage and increases product strength, thus providing the low-shrinkage, high-strength, and large ceramic plate.

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.
