In this paper, the particle size distribution of TiO_2 measured by a turbidimeter is compared with that of the micron photo sizer and, in succession, the validity of turbidimetry is discussed. After changes of the turbidity with time were measured, the particle size distribution was then evaluated indirectly from above data. Furthermore, the approximate formula of particle size distribution was calculated from an aspect of statistical analysis. In result, it was clearly observed that the particle size distribution calculated from the approximate formula was closely agreement with the ones measured by the turbidimeter and the micron photo sizer. It was, therefore, ascertained that the particle size distribution of powder was possible to be exactly measured by the method of turbidimeter.
