Abstract

Imogolite was studied by the scanning electron microscope. Imogolite which examined was separated from Kurayoshi pumice beds. The samples were dried successively in the sealed vessel at critical point of CO2. This drying method exceeds in preservation of natural surface of imogolite than that of air-drying.<BR>The form of imogolite was observed as fibres-like threads. The threads were curled and entangled forming nets which were piled up one above the other. The diameter of these threads ranged from 0.03 to 0.06 μm.
