摘要： CLAY PARTICLES OF MICRON OR SUBMICRON SIZE AND CONTAINING 5 TO 10 PERCENT MOISTURE ARE FED INTO ONE END OF A CONFINING PASSAGE BY APPLYING SHEAR FORCES THERETO,UNDER PRESSURE, IN A DIRECTION TRANSVERSE TO THE PASSAGE, WHICH COMPACTS THE CLAY BY ORIENTING THE MICROSOPIC CLAY "FLAKES" SO THAT THEY LIE SUBSTANIALLY IN PARALLEL DIRECTION, AND SUCH ORIENTATION IS MAINTAINED AS THE CLAY IS PUSHED ALONG THE PASSAGE WHICH IS OF UNIFORM SECTIONAL AREA AND SHAPE. AT THE OTHER END OF THE PASSAGE THE COMPACTED CLAY

IS DEFLECTED RADIALLY OUTWARDLY IN ALL RADIAL DIRECTIONS TO BREAK THE MASS UP INTO CHUNKS OR BODIES WITHOUT DISTRUBING THE ORIENTATION OF THE FLAKES IN THE BODIES. THESE CHUNKS ARE THEN FURTHER BROKEN UP INTO GRANULES WITHOUT DISTURBING THE INTERIOR PARTICLE ORIENTATION FOR USE IN FORMING DESIRED SHAPES BY ISOSTATIC PRESSING.

摘要： A process for the production of a ceramic article includes the steps of: (a) preparing a particulate mixture; (b) contacting the particulate mixture to water to form a humidified mixture; (c) pressing the humidified mixture to form a green article; (d) optionally, subjecting the green article to an initial drying step; (e) optionally, glazing the green article to form a glazed green article; (f) subjecting the green article to a heat treatment step to form a hot fused article; and (g) cooling the hot fused article to form a glazed ceramic article. The particulate mixture includes from 30 wt % to 80 wt % recycled aluminium silicate material. The particulate mixture has: (i) a d50 particle size from 10 μm to 30 μm; (ii) a d70 particle size of less than 40 μm; and (iii) a d98 particle size of less than 60 μm. Steps (c) and (f), and optionally steps (d) and (e) are continuous process steps.

摘要： 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.

摘要： 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.
