摘　　要：黑釉瓷在中国陶瓷史上占据重要地位,宋代建窑油滴釉瓷以其独特的釉色与斑纹备受推崇。为揭示油滴釉的组成特征及其呈色不同的内在原因,采用能量色散X射线荧光光谱仪(EDXRF)、色差计、扫描电子显微镜及其能谱仪(SEM-EDS)、显微聚焦拉曼光谱仪(Raman)、X射线光电子能谱仪(XPS)等测试手段对不同呈色油滴釉的组成、显微结构及烧制工艺进行分析。结果表明,宋代建窑油滴釉的硅铝比在6.77~11.15之间,与其他类型建盏瓷釉化学组成不同,油滴釉呈“高硅、高钾、低钙、低铁、低钛”的特征,暗示其配方独特。晶斑内外的元素分布存在明显差异,晶斑内富集的钙、铁、钛和磷等元素对晶斑的形成具有重要作用。不同呈色的油滴釉的化学组成未见明显区别,表明化学组成并非决定其呈色的主导因素,通过瓷釉中铁离子价态和胎色分析推断烧制气氛是影响析出晶体种类和尺寸的关键要素之一。当Fe^(2+)/Fe^(3+)比值较大时,胎色偏黑,以还原气氛为主,银白色晶斑是由聚集的ε-Fe_(2)O_(3)纳米晶或α-Fe_(2)O_(3)晶体薄膜对光产生强反射效应;当Fe^(2+)/Fe^(3+)比值较小时,胎色偏红,以氧化气氛为主,棕黄色和红棕色晶斑分别主要来源于5~10μm雪花状ε-Fe_(2)O_(3)和α-Fe_(2)O_(3)晶体的化学色。化学色与结构色的耦合效应能调控呈色,黄绿泛蓝色晶斑则主要是由100~200 nm的ε-Fe_(2)O_(3)晶粒瑞利散射与化学色耦合产生,而银白泛红棕色则是由α-Fe_(2)O_(3)晶体薄膜对光产生的全反射与化学色的结果。该研究阐明了宋代建窑油滴釉的组成和结构特征,揭示了其多样化呈色机制,为深入挖掘建窑黑釉瓷的科技内涵提供了重要依据,对铁系析晶釉的创新与开发具有参考价值。Black-glazed porcelain holds a significant place in the history of Chinese ceramics,with Song dynasty Jian kiln oil spot glazes being highly esteemed for their distinctive colors and patterns.To elucidate the compositional characteristics and underlying causes of the varying colors in oil spot glazes,we employed energy dispersive X-ray fluorescence(EDXRF),colorimetry,scanning electron microscopy with energy dispersive spectroscopy(SEM-EDS),micro-focused Raman spectroscopy,and X-ray photoelectron spectroscopy(XPS)to analyze the composition,microstructure,and firing processes of these glazes.The results indicate that the Si/Al ratio of Song dynasty Jian kiln oil spot glazes ranges from 6.77 to 11.15,distinct from other Jian ware glazes.These oil spot glazes are characterized by high silicon,high potassium,low calcium,low iron,and low titanium content,suggesting a unique formulation.There is a significant difference in elemental distribution inside and outside the crystalline spots,with calcium,iron,titanium,and phosphorus being enriched within them,playing a crucial role in their formation.No significant differences were observed in the chemical composition of oil spot glazes with different colors,indicating that composition is not the primary determinant of coloration.Instead,analysis of iron ion valence states in the glaze and body color suggests that the firing atmosphere is a key factor influencing the type and size of precipitated crystals.When the Fe^(2+)/Fe^(3+)ratio is high,the body color tends to be darker,indicating a predominantly reducing atmosphere.The silver-white spots are caused by strong light reflection from aggregatedε-Fe_(2)O_(3)nanocrystals orα-Fe_(2)O_(3)crystalline films.Conversely,when the Fe^(2+)/Fe^(3+)ratio is low,the body color tends to be reddish,indicating an oxidizing atmosphere.The brownish-yellow and reddish-brown spots primarily result from the chemical color of 5~10μm snowflake-shapedε-Fe_(2)O_(3)andα-Fe_(2)O_(3)crystals.The coupling effect between chemical and structural col
