Abstract
Small particles are produced by supporting a pair of elongated consumable electrodes coaxially in a housing so that corresponding ends of the electrodes are spaced apart across a gap. A potential difference is applied to the electrodes so that an arc ignited in the gap between the electrode ends gasifies the electrode material at the end. The gas is then cooled so that the gas condenses into small droplets which solidify into solid particles which are collected at a collection site.
