采用传统固相法制备了无铅熔剂包覆的硫化铈红色陶瓷颜料,研究了硫化铈/无铅熔剂质量比以及冷却方式对颜料呈色性能和热稳定性的影响。结果表明,当 m (硫化铈)/m (无铅熔剂)＝1∶1,并直接取出放入水中冷却的条件下,样品的包覆效果最佳,颜料表面形成致密的无铅熔剂包裹层。烧结后的样品具有很高的结晶度和红度值,因此有望作为生态红色颜料应用于陶瓷领域。
Lead-free flux coated Ce2 S3 red ceramic pigments were prepared by a conventional solid-state route. The impact of cerium flux mass ratio and cooling method on the coloring properties and thermal stability were investigated.The result shows that the coating property of samples is best when the cerium flux mass ratio was 1∶1,and taking out directly into water.In this case,dense protecting coating layers of lead-free flux form on the surface of the pigments.The sintered samples have high crystallinity and hues with Ce2 S3 successfully en-capsulated by lead-free flux,which have potential to be used as ecological red pigments for ceramic applications.
