  • Plasma synthesis of nanopowders
    Patent number: 8859931
    Abstract: A process and apparatus for preparing a nanopowder are presented. The process comprises feeding a reactant material into a plasma reactor in which is generated a plasma flow having a temperature sufficiently high to vaporize the material; transporting the vapor with the plasma flow into a quenching zone; injecting a preheated quench gas into the plasma flow in the quenching zone to form a renewable gaseous condensation front; and forming a nanopowder at the interface between the renewable controlled temperature gaseous condensation front and the plasma flow.
    Type: Grant
    Filed: March 8, 2007
    Date of Patent: October 14, 2014
    Assignee: Tekna Plasma Systems Inc.
    Inventors: Maher I. Boulos, Jerzy Jurewicz, Jiayin Guo, Xiaobao Fan, Nicolas Dignard
