In this study, a quantitative analysis for shape irregularity of ceramic particles was performed by applying the concept of fractal proposed ty B. B. Mandelbrot. Two types of ceramic particles processed by different methods were employed as the samples. Silhouette of the particle was repeatedly observed along three dimensional Cartesian axes, after which Richardson effects of the configurations of the respective silhouettes were normalized. In this normalized Richardson effect, characteristic aspect concerning the microscopic and macroscopic irregularities of the partcle shapes was found. The microscopic irregularity was successfully represented by fractal dimension, while the macroscopic one was evaluated by a parameter of macroscopic shape index.
