Abstract Scope |
There are three common production techniques for AlSc: Sc dissolution, aluminothermic reduction and electrolysis. These techniques have well known shortfalls, including time intensive, costly, composition, impurities, etc. FEA Materials has developed a process that overcomes some of these shortfalls. FEAM Process is a hybrid metallothermic/electrolysis process that enables low-cost production of AlSc. It can achieve Sc concentrations up to 8wt% in the alloy, runs continuously and maintains a material yield above 90%. A proprietary molten salt composition is used that is robust and self-correcting, overcoming the challenges with traditional electrolysis processes. The technology platform is modular, allowing for tuned production rates and flexible infrastructure requirements. It runs semi-continuously and sealed under inert atmosphere to keep tight control of the output streams and ensure a safe work environment. FEAM is currently producing 4kg of material per shift with the capability to expand to 50kg/shift within its existing facility. |
