Vacuum Furnace
- Manufactured by Vacuum Industries, this furnace is a Super VII model
Vacuum Furnace.
- The hot zone size is 8" x 8" x 20". The hot zone is an all metallic
construction with molybdenum heat shields and tungsten heating elements.
- The furnace is capable of reaching temperatures up to 1550oC.
- Heating profile controlled by Honeywell DCP 700 programmable
controller. Capability to define heat-up ramp rates, hold times and
temperatures, and cooling rates. Separate over-temperature control
system.
- A series of jets located in the heat shield and attached to the gas
supply lines allows quenching with argon gas.
- Temperature and pressures recorded on a Honeywell DPR 1500 Digital
Process Recorder.
- The vacuum system is comprised of a rotary vane pump, a 6" diffusion
pump, automated valves and vacuum control system. Typical vacuum levels
are 10-4to 10-6 millitorr.
- Capability of flow selected gas through system at partial pressure
levels of 10-1000 millitorr.
- Furnace is accessible from inert atmosphere glove box to allow inert
loading and unloading of samples
