摘　　要：分析了Fe和Cu在钧瓷紫釉和青釉中的存在形态。结果表明Fe在紫釉和青釉中都以Fe2 O3、Fe3O4 、FeO 3种形态存在 ;Cu在紫釉中以CuO、Cu2 O和少量的Cu存在。FeO和CuO共同作用的结果使钧釉呈现紫色。通过热力学分析了Fe和Cu的各种氧化物。并给出在不同CO2 /CO分压下各种氧化物的热力学状态图 。The shape of Fe and Cu existing in violet glaze and bluish glaze of Jun kiln were analyzed by XPS in this paper.The results indicated that Fe in the form of Fe 2O 3、Fe 3O 4 and FeO exist in violet and bluish glaze.Cu exists in violet glaze most in the shape of CuO,some of Cu 2O,and a small amount of Cu.The coloration of violet glaze is considered as the coalition result of FeO and CuO.Various oxides of Fe and Cu were analyzed with thermodynamics. The thermodynamic state graph of various oxides under different partial pressure ratio of CO 2 and CO was drawn.All the results will supply the theoretical basis for imitation of Jun kiln.
