Changes in the phase and chemical compositions, as well as the course of hardening during heating of mixtures with a phosphate binder of pyrophyllite raw materials from the Kul-Yurt-Tau deposit and for comparison of raw materials from the Ovruch deposit, have been investigated. It is shown that the behavior of these materials is similar. The optimal amount of binder has been determined to obtain a durable pressed semi-finished product. To achieve water resistance and the required strength of composites, they should be processed at temperatures of 500 - 600 ° C.
