• An experimental study of the size effects of particle compressive strength of brittle solids under slow rate of compression was carried out by using spheres made of two kinds of glassy materials and five kinds of minerals. The measurement of particle compressive strength was obtained by compression method of particles. The particle diameters of specimens ranged from about 10 cm to 0.0030 cm respectively. A summary of experimental results was as follows : Particle compressive strength of the glassy materials was linearly increased with the decrease of their volumes when the data are plotted on a logarithmic coordinate. Each relationship was simply expressed by the Weibull's equation. On the other hand, particle compressive strength of the minerals was increased along with a warped line with the decrease of their volumes on a logarithmic coordinate. The relationship was expressed by respective refractive line each having different gradients. This warpage may be due to the status of pre-existent cracks in the specimen.
