Recent progresses in particle-size analysis are reviewed and the matters that require attention to apply these method for clay partcles are discussed. Usually, clay partilces have unfavorable properties for particle analysis, such as submicron diameter, low sphericity, wide particle-size distribution and strong coagulation. To overcome these difficulties, it was suggeted that the folloing attentions are required for the applications for clays : 1) return back to the physical meaning of the particle-size measured by each method, 2) check the particle-size with electron microscope, 3) break coagulations using appropriate dispersant and ultrasonic wave and 4) check the reproducibility of the sizes several times with different treatment utilizing recent instrument with rapid analysis.
