Abstract
Structure and a method for producing very dense bodies from particulate materials. An electrically conductive drive member is positioned adjacent the particulate material. A significant magnitude of electrical current is caused to flow through the electrically conductive drive member. A magnetic field is established and large magnitudes of magnetic pressure are created, and pressure directly from or indirectly from the magnetic pressure is applied upon the particulate material, and the particulate material is compressed and compacted. In one embodiment of the invention electrical current creates a magnetic field which is applied to an electrically conductive pressure member which moves and applies compaction pressure upon the particulate material. Electromagnetic pressure in accordance with this invention may be applied to a compacted body of particulate material, and the compressibility and density of the body of particulate material is increased. Any one of numerous types of particulate material may be involved with regard to this invention.
