本手稿提供了光学显微镜、扫描电子显微镜和透射电子显微镜显微照片，显示了三种超细核石墨等级 IG-110、2114 和 ETU-10 的微观结构。这组微观结构数据展示了这些材料的微观结构，有助于区分这些石墨等级最重要的特征或相。特别是，微观结构数据说明了这些等级的填料和粘合剂形态。此外，通过光学显微镜和 X 射线计算机断层扫描对收到的和氧化的 IG-110 样品进行了表征。氧化 IG-110 的微观结构数据显示了氧化实验产生的孔隙率。这些显微照片和数据为核石墨的微观结构特征和氧化效应提供了独特的见解，可用于进行定量孔隙率分析。这组微观结构数据补充了相关手稿中描述的建模和表征，“使用多孔随机场来预测未氧化和氧化超细石墨的弹性模量（Arregui-Mena 等人，2022）。”
This manuscript provides optical microscopy, scanning electron microscopy, and transmission electron microscopy micrographs that show the microstructure of three superfine nuclear graphite grades IG-110, 2114 and ETU-10. This collection of microstructural data showcases the microstructure of these materials and helps to differentiate the most important features or phases of these graphite grades. In particular, the microstructural data illustrate the filler and binder morphology of these grades. Moreover, samples of as-received and oxidized IG-110 were characterized via optical microscopy and x-ray computed tomography. The microstructural data of oxidized IG-110 shows the porosity generated by oxidation experiments. These micrographs and data provide a unique insight into the microstructural features and oxidation effects in nuclear graphite and can be used to perform quantitative porosity analysis. This collection of microstructural data complements the modeling and characterization described in the associated manuscript, “Using porous random fields to predict the elastic modulus of unoxidized and oxidized superfine graphite (Arregui-Mena et al., 2022).”
