X 射线显微镜(显微 CT)是一种非破坏性的高分辨率成像技术.采用显微 CT 扫描和三维重建技术,对金元时期的钧釉瓷内部气泡和孔隙进行三维可视化和定量分析,得到了三维可视化分布图像与定量数据.研究发现,金元时期钧釉瓷釉层气泡尺寸相差大,且分布离散.其中,大于 100 μm的气泡主要分布在釉层中层;小于 100 μm的气泡分布在釉层表层,通过结合岩相分析与化学组成分析发现,该特征的形成与釉的高温黏度、烧成温度等因素有关.研究采用了显微 CT 扫描与三维重建技术,其是一种无损分析古陶瓷气泡与孔隙特征及工艺的新方法,该研究验证了显微CT在古陶瓷微观结构研究中的可行性和有效性,为古陶瓷制作工艺的科学分析、鉴定、保护和修复等方面提供重要的实验依据.
Application of Micro-CT Technique to the Microstructure Characterization of Jun Glaze Porcelain
X-ray microscopy(micro-CT)is a non-destructive high-resolution imaging technique.By using micro-CT scanning and 3D reconstruction technology,3D visualization and quantitative analysis of the internal bubbles and pores of Jun glaze porcelain in Jin and Yuan dynasties were carried out,resulting in 3D visual distribution images and quantitative data.It is found that size of the bubbles in the glaze layer of Jun glaze in the Jin Yuan period is very different.The bubbles larger than 100 μm are dispersed and mainly distributed in the middle layer of the glaze layer,while the bubbles smaller than 100 μm are distributed in the surface layer.Combined with petrographic and chemical composition analysis,the formation of the feature is related to the high temperature viscosity and firing temperature of the glaze.Micro-CT scanning for 3D reconstruction is a new non-destructive method to analyze the characteristics and processes of the bubbles and pores of ancient ceramics.This study verifies the feasibility and effectiveness of micro-CT in the study of the microstructure of ancient ceramics,providing important information and basis for scientific analysis,identification,protection and restoration of ancient ceramics.
