Problems solved by technology

[0006] For this reason, the technical problem to be solved by the present invention is that in the prior art, crystallization agents are used when preparing crystalline glazes, and non-uniform nucleation is carried out by using the residual nuclei in the glaze melt or the residual nuclei of seed crystals, and the particle size of the residual nuclei is difficult to accurately control , and then the crystal flower is difficult to control, the production conditions are harsh, the cost is high, and commercial production cannot be produced. Therefore, a preparation method and application of glaze for fast-fired crystal glazed ceramic tiles and ceramic tiles are proposed.

Abstract

The invention provides a glaze for fast-fired crystal glaze ceramic tile and a preparation method and applications of ceramic tile. The glaze comprises basic crystal glaze and a color developing agent, wherein the basic crystal glaze comprises the following raw materials: zinc oxide, titanium dioxide, quartz, cryolite, zinc phosphate, kaolin, and lead frit. A proper amount of zinc phosphate is introduced into the glaze to avoid the raw material frit treatment, which is carried out to ensure the residual amount of nucleating agent, the requirements on the glaze granularity are reduced, the manufacture technologies of crystal glaze and ceramic tiles are simplified, and the technical difficulties that the crystal glaze sintering technology is complicated, the crystal patterns are difficult to control, and the production cost is high are solved. Moreover, the addition amount of quartz and lead frit is precisely controlled to obtain crystal glaze art ceramic tiles which have the advantages of good crystallization effect, strong three-dimensional effect, and good artistic effect. The provided preparation method has the advantages of simpleness, lower sintering temperature, shorter period, and suitability for massive industrial production.
