Abstract
Structure and a method for producing very dense bodies of material from powderous materials. A powderous material is placed within an electrically conductive container. A solenoid encompasses the electrically conductive container, and a large magnitude of electrical current is caused to flow through the solenoid or coil. As the electrical current flows through the solenoid or coil, large magnitudes of pressures are created upon the electrically conductive container, and the electrically conductive container is compressed, and the transverse dimension thereof is reduced. Thus, the powderous material within the electrically conductive container is very firmly compacted. A body of superconductive material of any desired size and shape can be produced by this method by the use of superconducting powderous material.
