The results of research on the modification of exfoliated vermiculite by activated silica, obtained from raw vermiculite by acid treatment, are presented. It is shown that at annealing temperatures 1100 – 1200°C a high temperature phase (cristobalite) forms in the phase composition of the material obtained. The properties and phase composition of the ceramic vermiculite samples fabricated on the basis of modified vermiculite and refractory clay are presented.
