Recently, many kinds of abrasive tools using ultrafine grains are developed to mirrorfinish the surface. However, it is difficult to disperse the grains and the pores uniformly in such tool because of the aggregation peculiar to fineparticles. Therefore, the structure of agglomerates of three kinds of particle, grain, vitreous bond and organic substance has been discussed. The process used to generate the agglomerates is the diffusion-limited aggregation. As a consequence of the simulations, it has been found that the simulated agglomerate is similar in structure to the real one and the structure of agglomerates is affected by the component ratio.
