Abstract: Systems and methods for recovery of rare-earth constituents from environmental barrier coatings are provided. One method includes extracting rare-earth (RE) oxide constituents from a feedstock containing RE silicates and non-RE contaminants. The method includes leaching the REs from the feedstock into an acid to form an acid solution, performing an oxalate precipitation on the acid solution to form an RE oxalate hydrate, and separating the RE oxalate hydrate from the acid solution. The method also includes heat treating the RE oxalate hydrate to form an RE oxide containing the RE elements extracted from the feedstock.

Abstract: Systems and methods for recovery of rare-earth constituents from environmental barrier coatings (EBCs) are provided. One method includes for separating rare-earth (RE) containing constituents from a particulate feedstock containing a mixture of RE silicates and non-magnetic constituents includes disposing a collection member in a vicinity of the feedstock and magnetizing the collection member to generate a magnetic field sufficient to selectively attract the RE silicates to the collection member. The method further includes removing the RE silicates from the collection member.

Abstract: A process for treating an electrochemical cell is presented. The process includes charging the electrochemical cell in a discharged state to at least 20 percent state-of-charge of an accessible capacity of the electrochemical cell at a first temperature to attain the electrochemical cell in a partial state-of-charge or a full state-of-charge and holding the electrochemical cell in the corresponding partial state-of-charge or full state-of-charge at a second temperature. The first temperature and the second temperature are higher than an operating temperature of the electrochemical cell.
