    摘要： Various embodiments of high pressure presses and related methods of manufacturing and operating such presses are described. In one embodiment, a cubic press is described having press bases with spacers disposed between adjacent press bases. Sets of two or more tie bars are also disposed between adjacent press bases. The tie bars are placed in a state of compression while the spacers are placed in a state of compression. During operation, the press bases may become displaced relative to one another such that additional tension is experience by the tie bars while the amount of compression experienced by the spacer is reduced. The tie bars exhibit a relatively small cross-sectional area as compared to the cross-sectional area of the spacer.

    摘要： A cartridge assembly for connection to the frame of a high pressure, high temperature press, comprising a front end. The front end may comprise a back up with a conical portion intermediate and coaxial with an anvil and a piston. The anvil may comprise a proximal end in contact with the back-up and a distal end being adapted to form part of a pressurized chamber within the frame. The back-up may comprise a truncated cylinder comprising a first and second interface that are joined by a peripheral cylindrical wall. The cylindrical wall may also comprise a portion extending normally from the periphery of the first interface to a net concave portion of the cylindrical wall. The net concave portion may extend from the normal portion of the cylindrical wall to the periphery of the second interface which abuts the anvil.

    摘要： An improved high pressure apparatus can include a plurality of complementary die segments. The die segments can have inner surfaces which are shaped to form a die chamber upon assembly of the die segments. A pair of anvils can be oriented such that an anvil is at each end of the die chamber. To prevent the die segments from being forced apart during movement of the anvils, force members can be connected to the die segments. The force members can apply discrete forces to the die segments sufficient to retain the die segments in substantially fixed positions relative to each other during application of force by the pair of anvils. Using such a high pressure apparatus can achieve pressures as high as 10 GPa with improved useful die life and larger reaction volumes.
