Application Notes
  • The concept of continuous power feeding and processing can be realized by the use of Magnetic Fluid Sealed Swivel Coupling in line with a Volumetric Feeder and Rotary Furnace. Please view the assembling approach diagram and video in below.  
  • For CVD coating, you may choose our multi-channel Gas delivery system as Pic below right.
  • For CVD coating, you may choose our multi-channel Gas delivery system and automatic feeding system  as Pic below 
  • Ref Article: Scalable synthesis of silicon-nanolayer-embedded graphite for high-energy lithium-ion batteries
  • The tube furnaces with quartz tubes are designed to use under vacuum and ambient pressure < 0.2 bars / 3 psig / 0.02 MPa (relative pressure)
  • Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSIG for safe operation. Click here to learn the installation of a gas regulator.
  • Vacuum limit definition for all quartz tube furnaces: * Vacuum pressures may only be safely used up to 1000°C
