摘要： A method for manufacturing frying, grilling, baking, and/or cooking utensils involves creating a green body from powdery silicon carbide, carbon, fillers, binders, and additives using ceramic shaping methods such as pressing, isostatic pressing, hot pressing, casting, die casting, or injection molding. The green body is carbonized and subsequently infiltrated with a metallic silicon melt. Through a final infiltration firing, the green body, together with carbon, forms a silicon carbide bonding matrix, resulting in a dimensionally stable frying, grilling, baking, and/or cooking utensil of the highest stability without residual porosity and with a temperature resistance of up to 1,350° C. This method gives rise to the aforementioned cookware, produced through the described process.

摘要： A method of forming a protective coating includes providing a substrate including a major surface. The method further includes providing a top coat layer adjacent to the major surface of the substrate. The top coat layer includes a top coat surface distal to the substrate. The method further includes forming a plurality of slots in the top coat layer. The method further includes at least partially heating the top coat surface above a threshold temperature, such that a first portion of the top coat layer extending from the top coat surface partially melts to form a glazed layer, and a second portion of the top coat layer disposed between the glazed layer and the major surface of the substrate is not melted and includes at least a portion of each of the plurality of slots.

摘要： The present disclosure relates to a ceramic tile decorated with dry particles to give a three-dimensional pattern and a manufacturing method thereof. The manufacturing method comprises the steps of A: glazing a surface of a green body with a ground coat; B: decorating a surface of the ground coat of the green body to form a pattern; C: drying the green body; D: embellishing the green body with dry particles; E: spraying a protective glaze on the surface of the green body; and F: firing the green body after the green body is sprayed with the protective glaze of step E to produce the ceramic tile decorated with dry particles. The manufacturing method can make the ceramic tile produced have a clear pattern, distinct layers, low glaze glossiness, a good non-slip effect, an obvious sense of dry particles, a strong three-dimensional effect, rich colors, and stable properties.

摘要： A pre-sintered porcelain block for dental restoration; the pre-sintered porcelain block does not contain crystal phases and has a Vickers hardness of 0.5-2 GPa. Due to a hardness which is significantly lower than that of the porcelain block containing a lithium metasilicate crystal phase, the pre-sintered porcelain block may be processed by using dry machining and can simultaneously be processed by using wet machining when being mechanically processed into a dental restoration shape.
