Ceramic tiles may be prepared employing a process 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. The ceramic raw materials mixed and then subjected to wet grinding to produce a slip. The thus obtained slip is then subjected to spray drying.

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 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.

Disclosed are a semi-transparent ceramic sheet decorated through ink light-absorbance and a preparation method thereof. The semi-transparent ceramic sheet comprises a semi-transparent green body, an inner inkjet pattern layer infiltrating into the semi-transparent green body from an upper surface of the semi-transparent green body, a decoloration glaze layer located on the upper surface, and a surface pattern layer located on the decoloration glaze layer. The decoloration glaze layer is capable of decoloring the ink of the inner inkjet pattern layer. The semi-transparent ceramic sheet is provided with the decoloration glaze layer so that the inkjet decoration of the inner inkjet pattern layer cannot be displayed on the surface, and the decorative pattern on the surface of the green body is the surface pattern layer and the inner inkjet pattern layer is completely in the inner layer of the green body.

A vermiculite core for a vehicle may include vermiculite and pearlstone, an aluminum component for the vehicle may be manufactured using the vermiculite core including the vermiculite and the pearlstone, and a method for manufacturing the vermiculite core for the vehicle may include mixing the vermiculite and the pearlstone, injecting a mixture of the vermiculite and the pearlstone into a mold, and pressing the mixture using a presser.

The present invention relates to a non-spray-drying, dry-granulation process for making a ceramic particulate mixture comprising from 4 wt % to 9 wt % water, wherein at least 90 wt % of the particles have a particle size of from 80 m to 600 m, wherein the process comprises the steps of: (a) forming a precursor material; (b) subjecting the precursor material to a compaction step to form a compacted precursor material; (c) subjecting the compacted precursor material to a crushing step to form a crushed precursor material; and (d) subjecting the crushed precursor material to at least two air classification steps, wherein one air classification step removes at least a portion of the particles having a particle size of greater than 600 m from the crushed precursor material, and wherein the other air classification step removes at least a portion of the particles having a particle size of less than 80 m from the crushed precursor material.

The present invention relates to a health artificial pearl and a manufacturing method therefor and, more specifically, to: a health artificial pearl formed by spray-drying and pressure-firing a functional mineral that emits anions and radiates far infrared rays, so as to form a core with high compressive strength, and by coating the surface of the core with an artificial pearl composition, which is nontoxic to the human body; and a manufacturing method therefor. The method for manufacturing a health artificial pearl comprises: (S100) a material pretreatment step of wet-grinding a functional mineral that emits anions and radiates far infrared rays so as to form a wet-ground solution, and spray drying the wet-ground solution so as to prepare a powder for press forming; (S200) a press forming step of injecting, into a press forming apparatus, the powder for press forming so as to form a core, and high-temperature-firing the core; (S300) a core polishing step of polishing the high-temperature-fired core; and (S400) a coating step of coating the polished core with an artificial pearl composition.
