Abstract

A long afterglow ceramic with non-cracking glazed surface and preparation process are disclosed, the long afterglow ceramic with non-cracking glazed surface comprises a ceramic body and glaze materials, wherein the glaze materials include following raw materials: low temperature glaze water, long afterglow aluminate material, wherein low temperature glaze water includes the following raw materials: Australian spodumene, talc, limestone, borax, boric acid, Dehua quartz, sillimanite, kaolin, zinc oxide, wherein the Australian spodumene and sillimanite that constitute the raw materials of the lowtemperature glaze water have a very small thermal expansion coefficient, and the thermal expansion coefficient of the glaze materials can be reduced by the combination of the Australian spodumene andsillimanite, so that the thermal expansion coefficient is smaller than the thermal expansion coefficient of the ceramic body. During preparation process, firstly use the low temperature glaze water together with the long afterglow aluminate material, and frits formed by calcination can effectively reduce the firing temperature of the glaze to ensure the sintering temperature of the glaze is between 790 and 810 DEG C and to ensure the long afterglow effect of the luminous material in the glaze.

Description

technical field [0001] The invention belongs to the field of long afterglow porcelain preparation, and in particular relates to a long afterglow ceramic with no cracks on the glaze surface and a manufacturing process thereof. Background technique [0002] Long afterglow material, commonly known as luminous powder, is a kind of photoluminescent material. It refers to the material that can continue to emit light for a long time after the light source is turned off after being irradiated by sunlight and long-wave ultraviolet light for a period of time. Long afterglow material As a kind of "green light source material" for energy storage and energy saving, people pay more and more attention to it today when energy is increasingly scarce. Luminous rubber, luminous leather, luminous glass, luminous ceramics, luminous decoration, luminous crafts, etc. [0003] Luminescent ceramics made of long afterglow materials are a popular ceramic product at present. The long afterglow materia...
