Abstract

Na tetrasilsic mica synthesized by melting method has a large particle. If that mica was dispersed into water, it is characterized by having the high aspect ratio of 1000-2000. This feature is applied as film formation material and gas barrier material. Although alcohol is added in that case in order to accelerate dryness speed, condensation and viscosity increasing is observed. In this presentation, observation of the condensation by alcoholic addition to suspension is reported, and discuss about the phenomenon of change of viscosity.
