Operating Instructions

1. Connect the gas source, air compressor, and booster pump.
2. Open the right cover and load the material. Ensure the chamber is clean and free of foreign objects.
3. Inspect the oxygen-free copper sealing gasket. Ensure it is free of deformation, discoloration, corrosion, holes, and impurities. Also, check that the left and right flange sealing surfaces are clean and undamaged; use alcohol to clean if necessary.
4. Close the right cover and tighten the nuts using a torque wrench. Set the torque to 130Nm-160Nm for proper sealing.
5. Adjust the gas cylinder inlet pressure (≥5MPa) and set the air compressor driving gas pressure to 0.8MPa. Use the booster pump to increase the gas pressure inside the reaction chamber to 50MPa, maintaining it for some time to ensure no leakage.
6. For chamber cleaning, open the booster pump first, then open the exhaust valve to allow continuous gas flow for a thorough purge. After cleaning, close the exhaust valve first, then the booster pump.
7. Set the sintering process, paying special attention to the target temperature and set pressure.
8. Start the sintering process.
9. After sintering is complete and the furnace stops heating, wait for the material to cool down to a safe temperature before releasing the pressure.
   • Caution: Do not release pressure while the temperature is still high, as this may cause hazards. Manually open the exhaust solenoid valve only after cooling.

This ultra-high pressure high-temperature sintering furnace ensures high precision, safety, and operational efficiency, making it an ideal choice for research.
