Abstract

The invention belongs to the technical field of preparation of ceramic glazes, and in particular relates to a fast-firing polycrystalline multi-color crystalline glaze and its preparation method and application, in particular to a fast-firing polycrystalline multi-color crystalline glaze and a preparation method thereof, a The invention relates to a preparation method of a fast-firing polycrystalline multi-color crystalline glaze ceramic product, a fast-firing polycrystalline multi-color crystalline glaze ceramic product and a high-temperature firing method thereof. The crystalline glaze is prepared by calcining light calcium carbonate (calcium), calcining light magnesium carbonate (magnesium), calcining zinc oxide (zinc), calcining titanium oxide (titanium), kaolin (silicon), quartz (silicon), feldspar (potassium) , sodium) seven kinds of metal systems, make the glaze slurry in a supersaturated state, increase the crystallization speed of the crystalline glaze, expand the crystallization area, avoid the problems of easy flow glaze, smoking (the phenomenon of cloudy yellow and smoke), and make the crystalline glaze Under the premise of not affecting its performance, the temperature can be raised to the sintering temperature normally, and the temperature can be quickly lowered to normal temperature after the sintering, which shortens the preparation cycle and achieves the effect of energy saving and environmental protection.

Description

technical field [0001] The invention belongs to the technical field of preparation of ceramic glazes, and in particular relates to a fast-firing polycrystalline multi-color crystalline glaze and its preparation method and application, in particular to a fast-firing polycrystalline multi-color crystalline glaze and a preparation method thereof, a The invention relates to a preparation method of a fast-firing polycrystalline multi-color crystalline glaze ceramic product, a fast-firing polycrystalline multi-color crystalline glaze ceramic product and a high-temperature firing method thereof. Background technique [0002] Crystalline glaze is a product whose crystalline substance is in a saturated state after the glaze is melted at a high temperature during the firing process, and crystallization occurs after cooling, and crystals with beautiful patterns are precipitated. As early as the Song Dynasty, our country had fired precious crystal glazes such as "rust flower", "tea powd...
