中国古代人工颜料中国紫的模拟制备与热稳定性研究

中国紫是活跃在我国战国至秦汉时期的人工合成颜料，是我国古代科技史上重要的里程碑。学界对该类文物样品的成分分析进行了较充分的研究，但是对这类古代人工制品的传统制作工艺研究尚有不足。本项目结合前期研究成果，以探明中国古代固态烧结纯正中国紫的精细制造工艺为目的，使用水热法和固态烧结法两条路径实现中国紫的模拟制备与热稳定性研究。首先，水热法制备纯净中国紫，并以此出发，使用TG-DSC和变温XRD技术，实现中国紫的热稳定性研究，揭示中国紫的热稳定阈值。其次，使用固态烧结法，从原料（矿源、用量）和工艺（温度、时间）两个方面，探明纯正中国紫的精细制造工艺。本项目的开展，一方面可继续深入揭示两千多年前，我国古代人工颜料中国紫的发展与成熟，再现我国古人的聪明智慧与科技水平，提升文化自信和民族自信；另一方面也为我国古代其他同类型人工制品的相关研究提供借鉴。

Chinese purple is a kind of ancient artificial pigment in China which was widely used from the Warring States Period to the Qin and Han dynasties. It is also an important milestone in the history of Chinese ancient science and technology. The studies on the composition analysis of this type of cultural relic samples has been done adequately. However, the researches on the traditional manufacturing technology of such ancient artifacts is still insufficient. This project, combined with the results of previous researches, used hydrothermal method and solid-state sintering method to simulated prepare the Chinese purple and do the research on its thermal stability to explore the fine manufacturing process of solid sintered pure Chinese purple in ancient China. To begin with, we used hydrothermal method to prepare pure Chinese purple. Based on this, TG-DSC and Variable temperature XRD technology were used to study the thermal stability of Chinese purple and reveal the thermal stability threshold of it. What’s more, the solid-state sintering method is used to explore the fine manufacturing process of solid sintered pure Chinese purple in ancient China from raw materials (mineral source, dosage) and technology (temperature, time). On the one hand, the development of this project, reproducing the wisdom and scientific technology of our ancient people, can further reveal the development and maturity on the production process of Chinese purple, an artificial pigment in ancient China more than 2000 years ago to enhance our cultural and national confidence; On the other hand, it can also provide references for the studies of other artifacts of the same types in ancient China.
