  • Method and apparatus for making submicrom powders
    Patent number: 4762975
    Abstract: A process for producing ultrafine particles includes the steps of providing a consumable electrode having a rod or wire configuration, melting the tip of the electrode by means of electron bombardment, and applying an intense electric field to the molten tip to generate a beam of charged droplets. By heating the tip of the rod but avoiding melting of the tip and subsequently applying an electric field to the heated tip, an ion beam may be generated.
