技术领域
本发明涉及一种陶瓷色料,具体涉及一种铽掺杂Y4MoO9的黄色陶瓷色料及其制备方法,属于无机化学材料制备技术领域。
背景技术
陶瓷色料是指用于陶瓷制品着色装饰的材料,它能加强制品的艺术效果、提高制品的性能和档次,增加制品的销售价格。
黄色陶瓷色料一般分为铬黄、镉黄、镨黄、钒锆黄、钛黄等,大部分黄色陶瓷色料中都含有铅、镉、铬、锑等有毒有害的重金属离子,在生产过程中容易造成环境污染,且在高温环境中颜色会发生变化。目前,镨黄系列黄色陶瓷色料因色泽鲜艳、环境友好受到了极大的关注,但由于镨黄陶瓷色料的最高使用温度一般不超过1300℃,因而在高温应用上受到了限制。Y4MoO9呈色鲜艳,具有较好的热稳定性,是一种较好的黄色耐高温陶瓷色料。Y4MoO9虽然色饱和度L值较高,但略带蓝相(a为负值),表观显示为嫩黄色,在陶瓷色料的应用领域有其局限性。
发明内容
本发明的目的是提供一种铽掺杂Y4MoO9的黄色陶瓷色料及其制备方法,用以增加Y4MoO9黄色陶瓷色料的红相。本陶瓷色料呈色鲜艳稳定,色差变化小,耐高温,不含铅、镉、铬、汞等重金属元素,是一种环境友好的黄色高温陶瓷色料。同时本陶瓷色料生产工艺过程简单,设备要求低,无需水洗,对环境无污染,容易实现工业化生产。
本发明所采用的技术方案是:
一种铽掺杂Y4MoO9的黄色陶瓷色料,由下列质量份数的组份制成:氧化钇445~452份,三氧化钼144份,氧化铽1~10份,并具有以下颜色特征值:L=71.4~84.1,a=1.9~11.5,b=40.8~52.2。
一种铽掺杂Y4MoO9的黄色陶瓷色料的其制备方法,包括如下步骤:
(1)按照组成配比,称取一定质量的氧化钇、三氧化钼、氧化铽粉体,然后加入水或有机溶剂,在球磨机中研磨混合均匀后,将其置于烘箱中干燥,研磨后得到混合粉末;
(2)将上述混合粉末置于电阻炉中进行烧结,从室温到600℃时的升温速度为10℃/min,在600℃时保温30~60min;然后以5℃/min的速率升至1400~1600℃,保温1~6h,然后自然冷却;
(3)将上述烧结后的产物粉碎过400目筛,即得到铽掺杂Y4MoO9的黄色陶瓷色料。
上述有机溶剂为乙醇、丙酮中的一种或其混合物。
本发明相对于现有技术的有益效果是:
本发明公开的一种铽掺杂Y4MoO9的黄色陶瓷色料,呈色鲜艳稳定,色差变化小,在高温条件下稳定性好,且不含铅、镉、铬、汞等重金属有毒有害的元素,是一种环境友好的黄色高温陶瓷色料。同时本黄色陶瓷色料生产工艺过程简单,设备要求低,无需水洗,对环境无污染,容易实现工业化生产。
