Material Feeding & Melt Stirring   
|
- A ?50×120H mm quartz ante-chamber was installed on the top of the main chamber for sequentially adding source materials into the crucible without breaking the vacuum or atmosphere of the main chamber. Such a unique feature provides the opportunity for preparing metal alloys with compositions of different melting points
- The SS retractable stirring rod can reach and stir the melt inside the graphite crucible (stirring rod with alumina tip is available upon request, the additional cost will apply.)
- A gate valve is employed for isolating/open the ante-chamber from/to the main chamber when material adding or melt stirring is needed
- Material feeding port and tipping over tray diameter: ?30

Warning

|
- Attention: Protective inert gas must be continuously filled throughout the experiment in order to protect the graphite crucible and C thermocouple. The gas flow rate should be limited to < 200 SCCM ( or 200ml/min)
- Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation. Click here to learn the installation of a gas regulator
- Never heat the furnace while the gas release valve is closed and a positive pressure condition exists within the furnace chamber. The pressure gauge must be used to closely monitor the chamber condition at all times during the heating process; please open the gas release valve immediately once the chamber pressure has reached over 3 PSI to prevent unforeseeable damages
