VBF-1050X-H6 Compact Anti-Corrosive Vacuum Box Furnace for Sulfides and Halides Sintering up to 1050°C with Digital Temperature Controller
The VBF-1050X-H6 vacuum box furnace is engineered for precise sintering of sulfide and halide materials, particularly suited for lithium-sulfur battery development. Its compact design integrates a corrosion-resistant ceramic heating module within a stainless steel vacuum chamber, enabling controlled thermal processing under high vacuum conditions.
This furnace achieves a maximum temperature of 1050°C, with continuous operation up to 1000°C. The vacuum chamber supports vacuum levels down to 10⁻⁴ torr when paired with a turbopump (not included), ensuring minimal contamination during heat treatment. The system includes a quartz observation window and gas inlet/outlet valves for controlled atmosphere processing.
Key Features
- Anti-corrosive ceramic heating module (W10″ x D8″ x H5″) housed in stainless steel vacuum chamber.
- Maximum temperature of 1050°C with ±1°C temperature stability and 30 programmable segments.
- Vacuum capability down to 10⁻⁴ torr with KF25 vacuum port and mechanical vacuum gauge included.
- RS485 communication port and software for PC-based temperature control and monitoring.
- Quartz observation window (Ø25 mm) integrated into front door for process observation.
- Gas inlet and outlet valves for controlled atmosphere processing.
- Ni-Cr-Al resistance coil heating element embedded in ceramic to resist corrosion from sulfides and halides.

Typical Applications
This vacuum furnace is optimized for sintering sulfide and halide materials used in lithium-sulfur battery research and development. It is suitable for controlled atmosphere heat treatments requiring corrosion resistance and precise temperature control under vacuum.
Configuration & Operating Notes
The furnace includes a mechanical vacuum gauge and digital temperature controller with programmable segments. Vacuum pumps and crucibles (alumina or quartz) are optional and must be ordered separately. The power cable is supplied without a plug; users should install a plug suitable for their local power standards. The heating element is protected inside a ceramic chamber to prevent corrosion from reactive materials.
