  • What is Plasma?Fourth state of matterGas-likeConsists of neutral atoms/molecules, ions, and electronsHigh energy, highly reactive substanceElectrons have 10,000 K worth of energyActivates surfacesImage:

  • Plasma for Metal Treatment High Temperature Arc Plasma (up to 16000C) Ceramic Deposition

    Radio Frequency Induction Coupled Plasmas (5000C) Surface treatments for semiconductors

    Electrodeless Atmospheric Microwave Plasmas EAMP

  • AtmosphericPlasmaNon-equilibrium plasmaElectrons at 10-20,000 CIons, molecules at 60-80 CRelatively uniform energy distributionDoes not require special vacuum chambers like low pressure plasma

    ELIMINATION OF ORGANIC SOLVENTS FOR DEGREASING OF METAL COMPONENTS BY USE OF A NOVEL MICROWAVE PLASMAP. Aguirre, B. San Pedro, N. Wright, W. Hopkins, Global Symposium On Recycling, Waste Treatment and Clean Technology 04. Madrid.Jointly sponsored by INASMET, C-Tech Innovation, Phoenix Scientific Industries

  • APNEP ResearchExamined the effects of Atmospheric Non Equilibrium Plasmas of Oxygen, Nitrogen, Argon, and Mixtures.Treated standard industrial components contaminated with commercial oils and lubricants at loadings of 1-5 g/m2

  • APNEP ResearchVaried plasma flow rate, microwave output power, and exposure duration. Plasma jet temperatures averaged 200C.Achieved cleanliness equivalent to TCE vapor degreasing with an emission profile that met EU Industrial limits. Claimed 98-100% removal of oils.Paper left out key detail to determine exact operation costs.Nitrogen plasmas produce NOX, leading the focus to oxygen

  • APNEP ResultsElevated gas temperatures -10% evaporation captured with coalescing filters.Emission profile for Oxygen Plasma (10% radicalization) on components at 5g/m2 contamination level

  • For immediate release - 10 November 2004C-Tech Lands DTI Grant for APNEP Plasma DevelopmentC-Tech Innovation Limited has successfully obtained funding from the DTI to furtherdevelop its unique, Atmospheric Pressure, Non-Equilibrium Plasma (APNEP), which hasenormous potential in a wide variety of industrial and environmental applications.C-Tech has been awarded a Research and Development grant (formerly SMART award)for the ongoing development of the APNEP plasma. The DTI grants are provided to helpsmall and medium-sized businesses research and develop technologically innovativeproducts and processes, to generate new scientific or technical knowledge that will be
