MW-SPS-1400 Microwave Heated Spark Plasma Sintering Furnace with 1400°C Max Temperature and 100 MPa Pressing Pressure
The MW-SPS-1400 is engineered for advanced laboratory sintering tasks requiring rapid heating and high-pressure pellet pressing. It enables the densification of ceramic and metallic powders into solid pellets within a controlled atmosphere, either inert gas or oxygen, facilitating precise material property control. The system accommodates pellet diameters between 10 and 12.7 mm and achieves heating rates up to 100°C per minute, allowing efficient processing cycles.
This furnace integrates microwave heating via a water-cooled magnetron operating at 2.45 GHz, delivering microwave power up to 2500 kW (manufacturer verification recommended). The pressing mechanism uses a precision servo motor capable of applying loads up to 2000 kgf, corresponding to a maximum graphite die pressure of 100 MPa. Pressure is maintained with ±0.5 kg accuracy through PID control. The vacuum chamber is constructed from stainless steel with internal dimensions of 315 mm diameter and height, featuring quartz observation and vacuum ports for atmosphere control down to 10-5 Torr vacuum or up to 0.5 bar positive pressure.
