Novel conductive steel ring for synthesizing diamond by cubic press

The utility model relates to the technical field of high-temperature and high-pressure synthesis of superhard materials by a cubic press, in particular to a novel conductive steel ring for synthesizing diamonds by the cubic press, which comprises a steel cap and is characterized in that the steel cap is a special-shaped metal steel cap, a cylinder is arranged in the middle of the special-shaped metal steel cap, and the cylinder is provided with a steel ring. The periphery of the lower end of the cylinder is outwards provided with a brim, the upper part of the brim is provided with a pyrophyllite circular ring cake, the upper part of the pyrophyllite circular ring cake is provided with a dolomite circular ring cake, and the cylinder is internally provided with a dolomite cylinder to form a conductive steel ring body. The structure has the advantages of being simple to manufacture, environment-friendly, capable of effectively preventing ablation and melting of a part in contact with a heating body, capable of b
