FIELD: physico-chemical modification of substances under high pressures and temperatures. SUBSTANCE: installation has foundation supporting frame with inner spherical space. Frame consists of two stacking parts and encloses spherical shell, two parts of which are secured to corresponding parts of the frame thereby forming primary-pressure chamber with two separated hollows. Shell parts enclose punches, their outer parts being in the form of truncated pyramids with great spherical bases and positioned in a spaced relation to side surfaces. Truncated surfaces of pyramids form a space where inner punches are installed in contact with inner surfaces of outer punches through insulating spacers. Side surfaces of inner punches form gaps where deformable inserts are disposed, whereas inner surfaces of inner punches form compression chamber with disposed therein deformable container made of heat and electric insulating material with inner cavity for receiving material to be processed, height to width ratio of the compression chamber lying in the range 1.03 to 1.4. Inside the shell, there are means to overlap gaps between side surfaces of outer punches, which are electrically insulated from the latter. Arrangements are also available providing heating and measuring circuits and therefore automation of the overall process, arrangements for cooling outer and inner punches, and means for convenient removal and installation of deformable container with material. EFFECT: improved structure of installation. 43 cl, 27 dwg
