RTP-HFU-3000 High Vacuum Ultrafast Heating Furnace with Flash Sintering up to 3000°C
The RTP-HFU-3000 is engineered for rapid thermal processing tasks requiring ultrafast heating under high vacuum conditions. It is particularly suited for sintering carbon-based materials such as sheets or paper by applying flash sintering techniques inside a robust stainless steel vacuum chamber. This setup enables precise control of temperature and atmosphere, essential for advanced material research and development.
The furnace achieves temperatures up to 3000°C with heating rates exceeding 200°C per second, allowing extremely fast thermal cycles. Temperature is monitored and controlled using a high-accuracy infrared pyrometer through a quartz observation window, with options for manual or automated PID control. The system includes PC software for programmable temperature profiles and pulse frequency adjustments on the DC power supply.
