古陶瓷颜料中国紫的制备及表征

Preparation and characterization of an ancient ceramic pigment:Chinese purple

中国紫和中国蓝作为古陶瓷颜料中的典型代表,因其绚丽的色彩和独特的物理化学性能,受到了人们的广泛关注.本文采用共沉淀-水热法制备中国紫颜料前驱体,然后在不同温度下进行焙烧,最终获得性能较好的颜料产物.利用XRD,SEM和FTIR等对所得产物进行表征分析.最终结果显示,利用共沉淀-水热法制备的前驱体经过煅烧后所获得的颜料与未经煅烧样品相比,不仅色彩鲜艳,结晶度高,而且具有良好的微观形貌.该法与传统方法相比,降低了能耗,简化了操作,真正做到了低能高效.

Chinese purple and Chinese blue as the representative of ancient ceramic pigments have been widely concerned due to their brilliant colors and unique physical and chemical properties.In this paper,the ancient Chinese purple pigment precursor is prepared by hydrothermal and co-precipitation method and then sintered at different temperatures,resulting in pigment products with better performance.The obtained products were characterized by the XRD,SEM and FTIR measurements.The final results showed that the prepared pigment after calcination is not only colorful and well crystallized,but also has good morphology compared with the pigment without calcination.Generally speaking,this method can reduce energy consumption and can simplify process operation,and thus is an energy efficient method compared with traditional method.
