中国古代人造硅酸铜钡颜料模拟制备研究

Simulation Synthesis of Ancient Chinese Artificial Barium Copper Silicate Pigments

中国古代人造硅酸铜钡颜料主要包括三种,紫色的中国紫(BaCuSi2O6)、浅蓝色的中国蓝(BaCuSi4O10)和蓝色的中国深蓝(BaCu2Si2O7),这三种颜料在战国晚期至东汉晚期的中国大量使用。本文在对大量古代硅酸铜钡颜料样品分析研究的基础上,探讨了该类颜料的原料、烧制温度以及坩埚对模拟制备的影响。用石英粉作为硅源,铜绿和氧化铜作为铜源,硫酸钡、碳酸钡和氧化钡作为钡源,氧化铅作为铅源,模拟制备出了三种古代人造硅酸铜钡颜料,即中国紫(BaCuSi2O6)、中国蓝(BaCuSi4O10)和中国深蓝(BaCu2Si2O7)。

Ancient Chinese barium copper silicate pigments mainly comprise Chinese Purple （BaCuSi2O6）, Chinese Blue （BaCuSi4O10） and Chinese Dark Blue （BaCu2Si2O7）. They were widely used from the late Warring States period to the late Eastern Han Dynasty. Based on the analysis of large amounts of samples, this paper discusses the raw materials, firing temperature and crucible＇ s influence on the synthesis. The three pigments - BaeuSi2O6, BaCuSi4O10 and BaCu2Si2O7 - have been simulated by using quartz powder as silicon source, malachite and copper oxide as copper source, barium sulfate, barium carbonate and barium oxide as barium source, and lead oxide as lead source.
