    Abstract: The present disclosure relates to a low temperature, semi-continuous process for producing high purity rare earth metals and alloys in molten salts. Rare earth metals and alloys are reduced from the corresponding rare earth halide in molten salts in a semi-continuous process. An air stable pellet or ingot can be fed into molten salts and reduced through metallothermic reduction or electrolysis. The formation of an air stable feedstock minimizes handling concerns of the hygroscopic rare earth salts, allowing the reduction process to be run in a semi-continuous process. The process can optionally include the addition of alloying elements such as magnesium, iron and zinc reduce the required processing temperature.

    Abstract: An engineered composite system designed to be passive or inert under one set of conditions, but becomes active when exposed to a second set of conditions. This system can include a dissolving or disintegrating core, and a surface coating that has higher strength or which only dissolves under certain temperature and pH conditions, or in selected fluids. These reactive materials are useful for oil and gas completions and well stimulation processes, enhanced oil and gas recovery operations, as well as in defensive and mining applications requiring high energy density and good mechanical properties, but which can be stored and used for long periods of time without degradation.

    Abstract: A temporary well isolation device which has an axial passage that comprises a temporary housing having an internal cavity containing a chemical material and a temporary barrier or plug member that can be actuated by an external mechanism to allow fluid to flow into the internal chamber and contact the chemical material in the internal chamber. When the chemical material is exposed to fluid, the chemical material causes the temporary housing to corrode, dissolve, and/or degrade.
