The results of the preparation of strengthened syntactic carbon materials that can be used for industrial-grade heat insulation in conditions of heightened pressures and temperatures are presented. Strengthened syntactic carbon material is obtained by mixing hollow carbon microspheres, pre-treated with vanadium (III) chloride catalyst, with a phenol-formaldehyde binder with the addition of fine polydimethylsilane, molding the composition at low pressure, soaking the mold at 150°C for 2 h, followed by heat treatment in an inert environment at 375°C and final carbonization in combination with carbidization when the temperature rises at a rate of 100 K/h to 900°C. The physicomechanical and thermophysical characteristics were studied. Syntactic material can be used for the manufacture of heat-insulation products operating at high temperatures.
