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.
