ABSTRACT:
A liquid dielectric having a surface that is contacted by an end of an electrode so as to form a contact area between the electrode and dielectric liquid wherein said area is limited thereby providing a contact resistance that is large compared to the rest of the electrode and dielectric liquid. Current through the contact area causes local heating of the electrode at the contact and raises its temperature toward the melting point of the electrode. Heating causes an increase in resistance of the electrode region so that the area of contact can be increased further immersion of the electrode. The contact area becomes a high-energy region where high energy reactions can be sustained such as fusion and the erosion of the electrode to generate powder having a very fine particle size. When the intention is to generate powders, compounds may be dissolved in the liquid containing elements that combine with the eroding surface of the electrode to provide particles having a stoichimetric ration that depends on the concentration of the dissolved compound. In this manner, finely divided particles of Ba Ferrite are generated using an iron electrode and Barium Hydroxide dissolved in water.
