Changes of the phase and chemical compositions as well as the course of strengthening on heating of mixtures of pyrophyllitic raw material from the Kul’-Yurt-Tau deposit and, for comparison, the Ovruchskoe deposit with a phosphate binder are studied. It is shown that these materials exhibit similar behavior. The optimal amount of binder to obtain a strong pressed intermediate product is determined. The composites must be heat-treated at temperatures 500 – 600°C in order to attain water resistance and the required strength.
