VEF-1200 Molten Salts Reactor with Moveable Electrodes for Electrolysis, Up to 1200°C
The VEF-1200 is engineered to facilitate molten salt electrolysis reactions, particularly suited for Molten Salt Electrolytic Graphitization (MSEG). It addresses the need for precise temperature control and atmosphere management during high-temperature electrochemical processes involving molten salts.
This system integrates a hermetically sealed quartz vacuum chamber allowing atmosphere control and pressure regulation below 3 psig. The reactor accommodates a quartz crucible and features a manual vertical travel mechanism for loading and retrieving electrodes under an air-tight flange, ensuring minimal contamination and operational safety.
