概要

• 論文の詳細を見る

• Quanitative analysis for the shape irregularity of ceramic particles was performed by applying the concept of"Fractal"proposed by B. B. Mandelbrot. Two types of ceramic particles processed by different methods were employed as samples. Silhouette of each particle was repcatedly observed along 3-dimensional Cartesian axes, and then Richardson effect of the configuration of the respective silhouette was normalized by the perimeter. In this normalized Richardson effect, a characteristic aspect concerning the microscopic and macroscopic irregularities of particle shapes was found. The microscopic irregularity was successfully represented by a fractal dimension, whereas the macroscopic one was well evaluated by another parameter of macroscopic shape index introduced in this study.
