Abstract : A critical review is presented of recent attempts to produce high temperatures by electrically exploding metal wires. The phenomenology of the explosions is discussed, classification schemes are noted and scaling laws are compared with existing experimental data. A definite theoretical model of a fast explosion is developed, based in part on the controlling influence of the vaporization expansion wave. Problems of energy storage and transfer, electrical pulse shape and voltage breakdown are examined in order to develop the necessary background for a critique of high temperature experiments. These are found to be of two types, viz., 'hot wire' experiments with thermal energies up to 25 eV, and 'hot plasma' experiments with thermal energies possibly up to 350 eV. Inadequacies in various experimental approaches are discussed, and a list of criteria is offered by which future experiments may be judged. (Author)
