Cylindrical samples of tantalum are resistively pulse heated to high-temperature states along an isobaric path by capacitive discharge in a high pressure inert gas atmosphere. Using this technique samples may be heated to temperatures up to 10,000/sup 0/K at pressures up to 1.0 GPa. The transient (10/sup -4/ s) heating technique is employed to overcome stability problems. Our measurements are complemented by the additional capability to measure sound speeds in the hot expanded sample. Results of such measurements on tantalum at temperatures up to approx.6000/sup 0/K are presented along with several other quantities calculable from the sound speed data.
