发明名称 Verfahren zur Verdampfung von Metall, insbesondere zur Raffination von Zink und zur Herstellung von Metallstaub daraus
摘要 <p>A method of vaporizing metals comprises passing the liquid metal over the surface of an inert packing material in a stationary packed column, heat being simultaneously supplied directly to the metal film by means of electrical power via electrodes. The column is preferably packed with sized coke and the metallic vapour (e.g. Zn or Cd) is preferably supplied to a condensation system in an inert gas which latter is recirculated to shock chill the metallic vapour to provide metallic dust.</p>
