Abstract
The paper presents the results of obtaining hardened synthetic carbon materials that can be used for technical thermal insulation under conditions of elevated pressures and temperatures. The hardened syntactic carbon material is obtained by mixing hollow carbon microspheres pretreated with a catalyst with vanadium (III) chloride with a phenol-formaldehyde binder with the addition of fine polydimethylsilane forming the composition at low pressure, holding the mold at 150 ?C for 2 hours, followed by heat treatment in an inert medium at 375 ?C and final carbonation in combination with carbidization when the temperature rises at a rate of 100 ?C/h to 900 ?C. The physicomechanical and thermophysical characteristics are studied. Synthetic material can be used for the manufacture of thermal insulation products operating under high temperature conditions.
