合成了仿天目釉，并用X射线衍射仪、能谱仪、扫描电子显微镜和透射电子显微镜对其进行了分析。结果表明，釉主体为无定形硅酸铝，内嵌有大量含锰、钴、钒、铋、钨的金属氧化物多晶球形颗粒。釉表面形成了锰、钴、氧化铝的二维尖晶石树枝晶。提出了天目釉显微结构的形成机理。并对釉的色泽进行了讨论。研究发现，晶体厚度相关的光干涉可能是釉层出现彩虹色的一个重要因素。(C)2016年爱思唯尔有限公司和Techna Group S.r.l.版权所有。
Mimetic Tianmu glaze has been synthesised and analysed by using X-ray diffraction, energy-dispersive X-ray spectroscopy, scanning electron microscopy and transmission electron microscopy. It was found that the main body of the glaze was amorphous aluminium silicate with many embedded polycrystalline spherical particles of metal oxides containing manganese, cobalt, vanadium, bismuth and tungsten. Two dimensional spinel dendrite crystals of manganese, cobalt and aluminium oxide formed on the surface of the glaze. The formation mechanism of the microstructures in the Tianmu glaze is proposed. The colour appearance of the glaze has also been discussed. It has been found that the crystal thickness dependant light interference could be an important factor for the appearance of rainbow-like colour in the glaze layer.
