Electrothermal processing of tantalum capacitor powders

Abstract

A low-pressure arc discharger with the hollow cathode is a newly developed electrotechnological device for finely dispersed powders of particles having dimensions 50 micron and less. The discharger is useful for putting powder into a high reactive zone of a plasma column and for thermal and mechanical action on particles. In the NSTU, the plain scales of the splinter tantalum powder were gained experimentally. Based on the results of the experiments, several constructive solutions are proposed for the heating of powders with subsequent deformation of tantalum powder particles on the target.
