Abstract: A method of fluorinating a solid compound of a rare earth metal to produce a fluorinated rare earth metal compound in solid form includes reacting, in a reaction zone, a solid compound of the rare earth metal and gaseous hydrofluoric acid, thus producing the fluorinated rare earth metal compound in solid form. The reaction takes place, in the reaction zone, in the presence of exogenous water, which is water that is exogenous to water that is produced in the reaction zone as water of reaction due to the reaction of the solid compound of the rare earth metal and the hydrofluoric acid. Conditions of temperature and pressure in the reaction zone avoid condensation of the exogenous water, the water of reaction when present, and the hydrofluoric acid.

Abstract: Provided is a slurry for suspension plasma spraying, which is a spray material used for suspension plasma spraying in an atmosphere including an oxygen-containing gas, contains 5-40 mass % of rare earth fluoride particles having a maximum particle diameter (D100) of 12 μm or less, and contains one or more types of solvent selected from among water and organic solvents. A rare earth acid fluoride-containing sprayed film, in which process shift and particle generation hardly occur, can be stably formed on a base material by carrying out suspension plasma spraying in an atmosphere including an oxygen-containing gas. A spraying member provided with this sprayed film exhibits excellent corrosion resistance to halogen-based gas plasma.

Abstract: Synthesizing upconverting nanoparticles includes heating a precursor solution comprising one or more rare earth salts, an alkali metal salt or alkaline earth salt, and a solvent comprising a plasticizer in a microwave reactor to yield a product mixture, and cooling the product mixture to yield the upconverting nanoparticles. Core-shell upconverting nanoparticles are synthesized by combining the upconverting nanoparticles with a precursor solution comprising one or more rare earth salts, an alkali metal salt or alkaline earth salt, and a solvent comprising a plasticizer to yield a nanoparticle mixture, heating the nanoparticle mixture in a microwave reactor to yield a product mixture, and cooling the product mixture to yield the core-shell upconverting nanoparticles.

Abstract: The present disclosure relates to a method of making core-shell and yolk-shell nanoparticles, and to electrodes comprising the same. The core-shell and yolk-shell nanoparticles and electrodes comprising them are suitable for use in electrochemical cells, such as fluoride shuttle batteries. The shell may protect the metal core from oxidation, including in an electrochemical cell. In some embodiments, an electrochemically active structure includes a dimensionally changeable active material forming a particle that expands or contracts upon reaction with or release of fluoride ions. One or more particles are at least partially surrounded with a fluoride-conducting encapsulant and optionally one or more voids are formed between the active material and the encapsulant using sacrificial layers or selective etching. The fluoride-conducting encapsulant may comprise one or more metals. When the electrochemically active structures are used in secondary batteries, the presence of voids can accommodate dimensional changes of the active material.
