Plasma Torch Generation Of Spherical Nano Oxide Particles

Abstract
University of California scientists have developed a continuous plasma-based method of creating uniform nanosized (5-50nm) metal particles from microscale precursors. The low power, microwave atmospheric plasma torch exhibits a single torch production rate of 400mg/hr at 500W and demonstrates predictable and controllable modification of micron scale precursors aerosols of nearly all metals. This method generates minimal waste and is cost-effective as precursors are inexpensive.

Application(s)
Will be useful in markets requiring production of nanostructured metals including; 

• Automotive catalyst supports
• Bio-diagnostics and other sensors
• Chemical-mechanical planarization (CMP) slurries
• Magnetic recording tapes
• Optical fibers
• Sunscreens
• Drug delivery agents
• Quantum optical devices
• Environmental remediation
• Ceramics
• Semiconductors
