ABSTRACT:
An apparatus and method are disclosed for cleaning contaminated particulate material, such as, gas contaminated powder metal. Degassification is accomplished by introducing contaminated particulate material into a vacuum chamber which is connected to a vacuum pump. One or more electric fields are produced within the vacuum chamber by applying a potential across one or more sets of electrodes. The electrical field charges the contaminants and excites them so that the contaminants are separated for the particulate material and, in the case of a gaseous contaminant, are more easily removed from the vacuum chamber.
