ABSTRACT:
A high pressure, high temperature, piston-cylinder type apparatus which utilizes a soft, ductile, electrically conductive material as a driver element to transmit pressure from the piston to a charge in the cylinder. The driver element, preferably made of zinc or lead, or the like is placed in the pressure cylinder between an advanceable piston and a stationary sleeve of insulating material surrounding an electrically heatable core of charge material. As the piston is advanced, the driver element deforms into the end of the sleeve of insulating material and maintains pressure on the core with minimal deformation of the sleeve of insulating material.
