Application Notes |
- The heating temperature must be limited by a certain pressure level due to vessel material strength. Please refer to the specifications
- The pressure increases while the temperature is rising during operation. So you need to calculate the pressure changing towards your target temperature and set a safe value of pressure during the process
-
The furnace uses a tube with conflate-designed flanges.
- The safety pressure relief valve is available to be installed at the downstream side. Please click here for details.
- Small quartz or Alumina boat should be used to load the sample into the vessel. Please click the link below to order separately. Never place the sample directly onto the vessel without a crucible. Vessel service life could be reduced significantly if you do so.
- You may use gold or nickel foil to wrap the crucible boat to minimize the contamination to the pressure vessel.
-
  
- Optional torque wrench is available here to avoid overtightening the flange bolts
  - To measure the electric properties of thermoelectric ceramics under high pressure & temperature conditions, please order an alumina testing fixture and high-pressure electrical feedthrough (10Mpa Max.) with the furnace (additional fee will apply).

Safety Note
|
- Ni-based Superalloy ( Waspaloy or equivalent) is a reliable processing tube that can be used under high temperatures and high pressure. It has excellent ductility and tensile property so only creep deformation happens under the overpressure destruction test and is followed by a crack formed (usually at the hot zone at the center of the tube) to release the pressure. Brittle fracture won’t happen in the overpressure destruction test which means no tube explosion will happen under the overpressure of inert gas or safe gas or under other accidents causing overpressure of inert gas or safe gas.
