VMC3000UL Induction Heated Vacuum Furnace for Graphitization and Ceramic Sintering up to 3000ºC with Optional Molten Salt Electrolysis Capability
The VMC3000UL is engineered to address the demanding requirements of high-temperature processing such as graphitization of carbon fibers and sintering of advanced ceramics. Its vacuum environment combined with induction heating enables precise temperature control and rapid heating rates, facilitating material transformations at temperatures up to 3000ºC for short durations.
Beyond thermal processing, this furnace can be optionally configured for molten salt electrolysis by integrating an electrode feedthrough flange. This modification allows insertion of two or three electrodes into the heated graphite crucible, supporting electrochemical refining of noble or rare earth metals under controlled vacuum and temperature conditions.
