YLJ-SPS-1200 Compact Spark Plasma Sintering Furnace with 1200°C Max Temperature and 100 MPa Pressure for Pellet Pressing
The YLJ-SPS-1200 is engineered for laboratory-scale sintering tasks requiring precise temperature and pressure control on small pellet samples. It is particularly suited for processing battery materials, thermal compounds, electrical components, and metallic powders by applying simultaneous heat and pressure to pellets with diameters ranging from 6 to 12.7 mm.
This compact spark plasma sintering furnace integrates a stainless steel vacuum chamber with a quartz observation window, enabling controlled atmosphere sintering under vacuum conditions. The system supports a maximum operating temperature of 1200°C and can apply pressures up to 100 MPa via a precision servo motor and graphite die assembly, ensuring uniform densification of samples.
Key Features
- Maximum sintering temperature of 1200°C with rapid heating rates up to 200°C per minute.
- Pressure application up to 100 MPa controlled by a servo motor with ±0.5 kg accuracy.
- Stainless steel vacuum chamber (Ø315 mm × 315 mm height) with quartz observation window and multiple vacuum ports for flexible gas and vacuum integration.
- Programmable 30-segment temperature controller with touchscreen interface and RS-485 communication for PC monitoring and data logging.
- Includes a graphite die with 12.75 mm inner diameter; custom dies available upon request.
- Equipped with a digital temperature-controlled recirculating water chiller (75 L/min flow, 30K BTU/hr) for thermal management.
- Available with single-phase or three-phase power options; other power ratings can be customized.
