PURPOSE:To generate ultrahigh pressure easily by forming a divided sphere comprising >=4 truncated pyramids having spherical bases which are movable freely toward central direction with each other, and providing a vertically bisectable vessel covering the whole body of the divided sphere. CONSTITUTION:A positioning pin 8 is inserted into each pin hole 8a bored in the recessed part of the hemisphere 6 with the tip end of the pin protruded from the pin hole. Positioning of the divided body 5 is executed by assembling the divided body 5 by fitting the side surface of the divided body 5 to the pin 8. By this process, each divided body is positioned, and adjacent divided bodies 5 are held with a small distance corresponding to the dia. of the pin 8 from each other. If the divided body is divided into six parts, 3-4 bodies are first assembled, then, a material to be compressed such as graphite is contained in a pressurizing chamber 1 formed in the central part, then residual divided bodies 5 are assembled thereafter to form a spherical body as a whole which is a dividable sphere 2. |
