VMC3000UL Induction Heated Vacuum Furnace with Up to 3000ºC for Graphitization, Ceramic Sintering, and Optional Molten Salt Electrolysis
The VMC3000UL vacuum furnace is engineered for demanding laboratory processes requiring extremely high temperatures, such as carbon fiber graphitization and ceramic material sintering. Its induction heating system can rapidly elevate temperatures up to 3000ºC under vacuum conditions, enabling precise thermal treatment of advanced materials.
This furnace features a stainless steel vacuum chamber with double-layer water cooling and integrated observation windows for process monitoring. The included high-purity graphite crucible, with approximately 1-liter capacity, supports melting and sintering tasks, tested to handle up to 4 kg of iron. An optional electrode feedthrough flange allows conversion into a molten salt electrolysis furnace, facilitating noble or rare earth metal refining through insertion of two or three electrodes into the heated crucible.

Typische Anwendungsbereiche
The VMC3000UL is suited for advanced material processing including carbon fiber graphitization, high-temperature ceramic sintering, and refractory material treatments. Its optional molten salt electrolysis configuration supports refining of noble and rare earth metals by enabling electrode insertion into molten salts under vacuum and high temperature.
Hinweise zur Konfiguration und zum Betrieb
Optional accessories include a rotary vane vacuum pump for rough vacuum, turbopump for high vacuum, recirculating water chiller with >15 kW cooling capacity, Eurothermo temperature controller for enhanced accuracy, argon gas purifier to reduce impurities below 1 ppm, and electrode feedthrough flange for molten salt electrolysis applications.
Safety features incorporate automatic protections against water pressure loss, overheating, and over-power conditions. The graphite crucible is consumable and should be replaced as needed. The furnace requires a stable three-phase power supply and proper cooling water circulation for safe operation.
