Abstract

In continuation of our investigations determinations have been made of the chemical and mineralogic composition, of the viscosity of suspensions, and of the size and morphology of the particles of bentonites, of which three kinds contained free silica in the form of quartz, one was a pure montmorillonite, whereas four contained morntmorillonite with additions of crystobalite and also a small percentage of quartz. The measurements of viscosity have shown that suspensions of bentonites containing free silica, chiefly as crystobalite, have a smaller structural viscosity and thyxotropy.
