Abstract: The diamond and cement materials to be sintered are placed in a hermetic graphite sheathing which is, in turn, arranged inside a sheathing of some low-melting metal. The latter is to be made from a metal whose melting point is lower than the temperature at which diamond will be sintered with the cermet material. The filled-up graphite sheathing is placed into a high-pressure reaction chamber and heated up until the low-melting metal gets soft. Thereafter the temperature and the pressure are raised until they are adequate for diamond to be sintered with cermet material. The softened sheathing of the low-melting material is a hydrostatic medium which provides for a uniform distribution of pressure and temperature over the entire volume of materials being sintered.
