摘要： A device for the high pressure densification of superconducting wire from compacted superconductor material or superconductor precursor powder particles, has four hard metal anvils (5, 6, 7, 8) with a total length (L2) parallel to the superconducting wire, the hard metal anvils borne in external independent pressure blocks (9, 10, 11), which are in turn either fixed or connected to high pressure devices, preferably hydraulic presses. At least one of the hard metal anvils is a free moving anvil (6) having clearances of at least 0.01 mm up to 0.2 mm towards the neighboring hard metal anvils (5, 8), so that no wall friction occurs between the free moving anvil and the neighboring anvils. This allows for high critical current densities Jc at reduced pressure applied to the hard metal anvils.
