Dry granular glaze, ceramic tile with starlight effect and preparation method of ceramic tile

The invention provides dry granular glaze, a ceramic tile with a starlight effect and a preparation method of the ceramic tile. The dry granular glaze is formed by compounding zirconium-containing frit dry granules I and zirconium-containing frit dry granules II. The zirconium-containing frit dry particles I and the zirconium-containing frit dry particles II contained in the dry granular glaze both contain rich zirconium-containing substances, and zirconium in the dry granular glaze can be separated out in a crystal form in the high-temperature firing and cooling process, so that the glaze surface prepared by taking the dry granular glaze as a raw material has a plurality of fine granular flash particles on the surface, and the glaze surface has a good flash effect. Moreover, the glaze surface is fine in color, natural and vivid. 本发明提供一种干粒釉、具有星光效果的瓷砖及其制备方法。该干粒釉由含锆熔块干粒Ⅰ和含锆熔块干粒Ⅱ复配而成。在本发明的干粒釉所含有的含锆熔块干粒Ⅰ和含锆熔块干粒Ⅱ中，皆含有丰富的含锆物，在经历高温烧成、冷却的过程，干粒釉中的锆能够以晶体的形式析出，从而使采用该干粒釉作为原料制备的釉面表面具有很多细小颗粒状的闪光颗粒，呈现星光钻石效果，且釉面色彩细腻、自然逼真。
