Imogolite is nano-tube type aluminum silicate that exists naturally. Imogolite is one dimensional like crystal, so several broad peak are shown in XRD profile of Imogolite. Therefore the structural study of Imogolite cannot be done in a present state. Structure model of Imogolite is proposed, but this structure model is the one made by making good use of several data, that is morphorogy from TEM observation, electron diffraction pattern, X-ray diffraction pattern, state of Si coordination, chemical composition and density. In this paper, proposed structural model, several data in order to make structure model, inner and outer diameter of Imogolite tube and calculation result by molecular dynamics method are shown. In addition, behavior of dispersion and coagulation and water vapor adsorption property of Imogolite are shown.
