Recommendations for further scientific research to enable the development of recovery of the rare-earth and magnet recycling are also presented. Keywords Spent magnet recycling High temperature Rare earth Pyrometallurgy The only rare-earth transition-metal binary with this structure is L which is ferromagnetic with a cobalt moment of μ Β and Curie temperature T C = K (Buschow and Velge, ). Among the rare-earth–3d compounds it has the highest 3d-metal content and is of potential interest for :// Abstract. High temperature is an important means for inorganic syntheses of novel compounds, materials, and high-temperature phases. In this chapter, we highlight the various important aspects in high-temperature inorganic synthesis, along with their recent progress, such as preparation of rare earth compounds and materials at high temperature, sol–gel process, and precursors in high

High-purity ( mass%) rare earth compounds (e.g., oxides) are produced from these ores by physical concentration, leaching, solution purification, solvent extraction separation, and individual rare earth compound precipitation. About 40% of all rare earth production is used in metallic form—for making magnets, battery electrodes, and ://   A refractory material or refractory is a material that is resistant to decomposition by heat, pressure, or chemical attack, and retains strength and form at high temperatures. Refractories are inorganic, nonmetallic, porous, and heterogeneous. They are typically composed of oxides of the following materials: silicon, aluminum, magnesium, calcium, and ://   High-temperature superconductors (abbreviated high-T c or HTS) are operatively defined as materials that behave as superconductors at temperatures above nearly °C ( °F).. This is in fact the lowest temperature reachable by liquid nitrogen, one of the simplest coolants in cryogenics. All superconducting materials known at ordinary pressures currently work far below ambient   Handbook on the Physics and Chemistry of Rare Earths: Including Actinides, Vol the latest release in this continuous series that covers all aspects of rare earth science, including chemistry, life sciences, materials science and physics, includes interesting chapters on Forensic applications of rare earth materials, and Rare earths, the seventeen-position :// /handbook-on-the-physics-and-chemistry-of-rare-earths.

Their natural occurrence is strongly dependent on geological circumstances, and only in a few locations are they found in sufficient quantity and~/media/shared/documents/policy/Rare Earth Elements briefing.
