As-recived samples of limestones (from Kuzuu, Tochigi Prefecure) and shells (clams from Ariake) were calcined at 1010°C, crushed and screened, followed by hydrothermal treatment at 110°C in an autoclave. The resultant ashes were analyzed by various methods.<BR>Results obtained are summerized as follows : <BR>(1) Na<SUP>+</SUP> ion concentrations were found to be 0.386 ppm in limestones and 67.004 ppm in shells. <BR>(2) The H<SUP>+</SUP> ions (proton) were detected in shells by the Ion Micro-analyzer, indicating the presence of organic substances in shells.<BR>(3) Intensity ratios of the powder X-ray diffraction patterns were different, (001) diffraction intensity of the shell ash was extremely larger than that of the lime.<BR>(4) Electron Microscope observations revealed that the lime ash consisted of spindle and irregular-shape particles, while particles in the shell ash mostly had hexagonal plate-shape, and the average particle size of the shell ash was about 10-20 times as large as that of the lime.
