摘要/Abstract

摘要： 建窑油滴釉是中国古代最典型的铁系析晶釉之一,明晰氧化铁对析晶釉呈色与析晶的影响规律,能够为开发与创新多种呈色效果的铁系析晶釉提供科学依据和理论指导。本文采用XRD、Raman、SEM和EDS等测试方法,探究了不同氧化铁含量对釉熔体中析出晶体显微结构和釉面呈色的影响,揭示了釉层晶体结构对呈色的作用机制。结果表明,随着氧化铁含量增加,釉面析出棕黄色-银蓝色-银白色-银白泛红棕色的晶斑,晶斑呈色是由晶体的化学色与结构色耦合而成。晶斑中间区域的铁元素富集度高于边沿区域,优先发生ε-Fe₂O₃向α-Fe₂O₃的相变,形成不同的呈色效果。中间区域先析出2~4 μm的叶状ε-Fe₂O₃晶体,呈棕黄色;随着氧化铁含量增加,釉层中析出与釉面平行定向排列的棒状α-Fe₂O₃晶体,形成晶体薄膜,对光产生强反射而呈银白色;随着氧化铁含量继续增加,釉层中析出10~20 μm的树枝状α-Fe₂O₃晶体穿透晶体薄膜,薄膜产生的结构色(银白色)削弱,α-Fe₂O₃的化学色(红棕色)增强,耦合呈银白泛红棕色。边沿区域先析出大量30~50 nm的晶粒,产生瑞利散射,呈蓝色;随着氧化铁含量增加,表层棒状晶体也形成晶体薄膜,薄膜下层析出100~200 nm的板状纳米晶体,形成非晶光子晶体,产生相干散射呈蓝色,与反射的银白色耦合呈银蓝色。

Abstract: Jian kiln oil-spot glaze is one of the most typical iron crystal precipitation glazes in ancient China, and it is important to clarify the influence of iron oxide on precipitation glazes coloration and crystal precipitation, to provide a scientific basis and theoretical guidance for the development and innovation of iron crystal precipitation glazes with a variety of coloration effects. In this paper, XRD, Raman, SEM and EDS testing methods were used to investigate the microstructure of the precipitated crystals in glaze melt and the change rules of glaze coloration with different iron oxide content, and to reveal the mechanism of the glaze crystal structure on coloration. The results show that with the increase of iron oxide content, the glaze surface precipitates brownish-yellow, silver-blue, silver-white, silver-white and reddish-brown crystal spots, and the crystal spots are colored by chemical color and structural color coupling effect of crystals. The iron enrichment in the middle area of crystal spot is higher than that in edge area, and the phase change from ε-Fe₂O₃ to α-Fe₂O₃ takes place preferentially, forming different color effects. The middle area first precipitates 2~4 μm leaf-shaped ε-Fe₂O₃ crystals, with brownish yellow. With the increase of iron oxide content, the glaze layer precipitates with the glaze surface parallel to the directional arrangement of rod-shaped α-Fe₂O₃ crystals to form crystalline thin film, which produces a strong reflection of light, being silver-white. When the iron oxide continues to increase, the glaze precipitation of 10~20 μm dendritic α-Fe₂O₃ crystals penetrates the crystalline thin film, the structural color (silver) produced by the film is weakened, and the chemical color of α-Fe₂O₃ (reddish brown) is enhanced. The coupling is silver-white with reddish brown. The edge area first precipitates a large number of 30~50 nm grains, resulting in Rayleigh scattering as blue. With the increase of iron oxide content, the surface layer of rod-like crystals also forms a crystal film and the lower layer of film precipitates 100~200 nm plate nanocrystals to form amorphous photonic crystals. The coherent scattering is blue, and the reflected silver-white is coupled with silver blue.

Key words: iron oxide, oil-spot glaze, amorphous photonic crystal, structural color, chemical color, crystallization
