Jade color-changing ceramic dry granular glaze, ceramic tile and preparation method of ceramic tile
The invention discloses a jade color-changing ceramic dry granular glaze, a ceramic tile and a preparation method thereof, the ceramic dry granular glaze comprises the following raw material components: jade dry granules and color-changing dry granules, the jade dry granules are baryta feldspar type jade dry granules, and the content of BaO in the chemical composition of the jade dry granules is 5-10 wt%; the chemical composition of the color-changing dry particles contains B2O3 and silver halide. Micro-nano crystals dispersed in the jade dry particles form a jade semi-transparent effect, silver halide in the color-changing dry particles is decomposed by ultraviolet light to form dispersed Ag < + > colloid which preferentially occupies distorted large gaps, and the dispersed Ag < + > colloid and the micro-nano crystals in the jade dry particles form a scattering micro-area with a larger size, so that the opacifying effect of the glaze layer is improved, the transparency of the glaze layer is reduced, and the glaze layer is more transparent. Therefore, the jade effect of the glaze layer is changed; and after low-temperature heat treatment, dispersed Ag < + > colloid is separated from large gaps and is combined with halogen ions again, so that the size of a dispersed micro area in the glaze layer is reduced, and the semitransparent effect of the glaze layer is recovered.
本发明公开了一种玉质变色陶瓷干粒釉、陶瓷砖及其制备方法，该陶瓷干粒釉的原料组分包括玉质干粒和变色干粒，其中：玉质干粒为钡长石型玉质干粒，玉质干粒的化学组成中BaO的含量为5‑10wt％；变色干粒的化学组成中含有B2O3和卤化银。玉质干粒中弥散的微纳米结晶形成具有玉质半透效果，变色干粒中的卤化银经紫外光的分解后形成弥散的Ag+胶体优先占据畸变的大空隙，与玉质干粒中的微纳米结晶组成更大尺寸的散射微区，增加釉层的乳浊效果，降低釉层的透明度，从而改变釉层的玉质效果；而经低温热处理后，弥散的Ag+胶体从大空隙中脱离出来，重新与卤素离子结合，降低釉层中弥散微区的尺寸，恢复釉层的半透明效果。
