It includes two-sided top presses and polyhedron pressure chamber devices. Polyhedron pressure chamber devices include tetrahedron presses, hexahedron / top presses, and octahedron presses (also known as spherical segmentation high-pressure devices). Tetrahedron pressure chambers are basically no longer used. Hexahedron top presses are divided into hinged and pull-rod types. The maximum pressure that can be achieved by hexahedron and octahedron pressure chambers is about 15-30GPa. They are produced by several companies in China. The hexahedron top press is the most widely used large-cavity press in China. This press has the advantages of strong self-centering, low cost, and easy operation. It is the main equipment for synthesizing superhard materials such as diamond and cubic boron nitride (cBN) in China.
