Abstract

The invention discloses a heat-resistant ceramic edible vessel capable of being burnt over open flame and a production method thereof. A blank body of the heat-resistant ceramic edible vessel comprises kaoline, spodumene, lithium pottery stone, carbon-free silicon whiskers, bentonite, cured steatite and clay. The production method comprises the following steps that: the carbon-free silicon whiskers are dispersed by a mechanical low-speed ball-milling method, water is used as the ball milling media, the rotating speed adopted in the ball milling process is 250r / min, the weight ratio of materials to balls to water is 1 / 2 / 1.2, the ball milling time is 3 to 4 hours, the materials are dried into dry materials after ball milling completion, and the preparation method also comprises the following steps of material proportioning, ball milling through adding water, sieving, deironing, filter pressing, pugging, forming, drying, biscuiting, glazing and sintering. The product has extremely high heat resistance and mechanical strength, and the heat stability reaches the goal that, the vessel cannot be popped through once heat exchange in water with the temperature being 800 DEG C to 20 DEG C.

Description

technical field [0001] The invention relates to ceramics and a production method thereof, in particular to a heat-resistant ceramic edible vessel which can be burned on an open flame and a production method thereof. Background technique [0002] Ceramic edible utensils are widely used in families, hotels and restaurants due to their advantages of hygiene and easy cleaning. With the continuous improvement of people's living standards, it is required to provide more types of ceramic edible utensils, especially heat-resistant ceramic edible utensils that can be directly burned on an open flame, such as ceramic casserole pots, pots, kettles, etc. The international market has high requirements on the performance of heat-resistant ceramic edible utensils, which must be dry-fired to 800°C and put into normal temperature water without cracking. China Patent Authorization Announcement No. CN100567205C, the announcement date is December 9, 2009, the name of the invention is "a kind o...
