使用适当的断层扫描装置获得了不同细胞陶瓷的x射线断层扫描图像。样品的孔尺寸范围很广（μ m ~ mm），但多孔率范围很窄（75 ~ 85 vol.%）。对图像进行了处理，以检索陶瓷的局部部分。将该测量值的平均值与基于光学显微图像分析的标准方法进行了比较。利用三维数学形态学对图像进行处理，得到了孔隙和陶瓷的厚度分布。将这些粒度测量的平均值与光学和电子显微镜测量值进行比较。(c) 2006 Elsevier Ltd.版权所有。
X-ray tomography images of different cellular ceramics have been obtained using appropriate tomography setups. The samples exhibited a wide range of cell sizes (mu m to mm) but a narrow range of porous fraction (75-85 vol.%). The images have been processed to retrieve the local fraction of ceramic. The average value of this measurement have been compared with a standard method based on image analysis of optical micrographs. The thickness distribution of both pores and ceramics was also retrieved using three-dimensional (3D) mathematical morphological operation on the images. The average value of these granulometry measurements was compared to optical and electron microscopy measurements. (c) 2006 Elsevier Ltd. All rights reserved.
