Low-temperature fluoride-free method for preparing vanadium-zirconium blue ceramic pigment

The invention discloses a low-temperature fluoride-free method for preparing a vanadium-zirconium blue ceramic pigment, which comprises the following steps: by taking a salt raw material as a reaction precursor, promoting the formation of an in-situ mineralizer through a mechanochemical reaction generated during physical grinding, and then carrying out heat treatment, washing and drying to obtain the target product vanadium-zirconium blue ceramic pigment. The raw materials used in the method are low in price, the operation process is simple and easy to control, the preparation period is short, pollution is small, the reaction temperature is low, and the prepared powder is good in dispersity, high in crystallinity and suitable for large-scale production. The prepared pigment powder is obvious in blue hue, stable in color generation in glaze and expected to be further applied to the field of ink-jet printing. 本发明公开了一种低温无氟制备钒锆蓝陶瓷色料的方法，该方法以盐类原料为反应前驱体，通过物理研磨时发生的机械化学反应促进原位矿化剂的形成，后经热处理、洗涤、干燥即得到目标产物钒锆蓝陶瓷色料。该方法所用原料价格低
