La this study, the particle size distribution of the three samples whose exchangeable cations are different, is found by two different techniques. One of the techniques uses the absorption of X-ray and the other one is the diffraction of laser ray. The obtained data are commented by considering the kind and, the amount of the exchangeable cations.
