摘要： A powder comprising rare earth element fluoride particles having an aspect ratio of up to 2, an average particle size of 10-100 μm, a bulk density of 0.8-1.5 g/cm3, and a carbon content of 0.1-0.5 wt % is amenable to atmospheric plasma spraying. An article obtained by spraying the rare earth fluoride spray powder to a substrate undergoes few partial color changes and performs well even when used in a halogen gas plasma.

摘要： The present invention is a method of recovering neodymium (Nd) from waste by-products of rare earth magnet manufacture. Two main waste by-products, NdFeB swarf and NdFeB slag, are treated by two respective chemical schemes as described above. However, the only major consumption of chemical compound in both schemes is hydrofluoric acid (HF). The present invention scheme for NdFeB swarf recovery is characterized by using acetic acid (HC.sub.2 H.sub.3 O.sub.2) having a pK value of approximately 4.7. The present invention scheme for NdFeB slag recovery is characterized by using sulfamic acid electrolyte bath having a pH value of approximately 2.7. The moist neodymium trifluoride (NdF.sub.3) produced by both schemes can be dried by using the same microwave radiation technique to produce dry neodymium trifluoride (NdF.sub.3) which contains less than 3% moisture.

摘要： A particulate mixture of Fe.sub.2 O.sub.3 and RE.sub.2 O.sub.3, where RE is a rare earth element, is reacted with an excess of HF acid to form an insoluble fluoride compound (salt) comprising REF.sub.3 and FeF.sub.3 present in solid solution in the REF.sub.3 crystal lattice. The REF.sub.3 /FeF.sub.3 compound is dried to render it usable as a reactant in the thermite reduction process as well as other processes which require an REF.sub.3 /FeF.sub.3 mixture. The dried REF.sub.3 /FeF.sub.3 compound comprises about 5 weight % to about 40 weight % of FeF.sub.3 and the balance REF.sub.3 to this end.

摘要： A colour-free crystal of alkaline earth or rare earth fluorides is obtained by melting and solidifying the fluorides in the presence of the vapour of CoF3 and/or MnF3. Fluorides of Mg, Ca, Sr, Ba, and all the rare earths La-Lu are specified, and mixtures, e.g. BaF2 with 10-30% CaF2. They may be synthetic (obtained by reacting acetate, carbonate, or nitrate with HF) or natural, e.g. fluorspar, and may be solid bodies grown previously from a melt but having an optical defect, or may be comminuted. The CoF3 or MnF3 in amounts of 0.25-2% b.w. of the charge is placed in a vented cup above the fluoride charge in a crucible, and vaporizes as the charge melts. The crucible is then lowered into a cooler zone across a sharp temperature gradient to effect crystal growth. The melt may also include 1-4% b.w. lead fluoride with or without PbO or Pb3O4 and Pb metal, or 0.05-0.2% V metal; alternatively the additive metal may be placed in a vented cup.ALSO:A colour-free crystal of alkaline earth or rare earth fluorides is obtained by melting and solidifying the fluorides in the presence of the vapour of CoF3 and/or MnF3.

摘要： Monodisperse particles having: a single pure crystalline phase of a rare earth-containing lattice, a uniform three-dimensional size, and a uniform polyhedral morphology are disclosed. Due to their uniform size and shape, the monodisperse particles self assemble into superlattices. The particles may be luminescent particles such as down-converting phosphor particles and up-converting phosphors. The monodisperse particles of the invention have a rare earth-containing lattice which in one embodiment may be an yttrium-containing lattice or in another may be a lanthanide-containing lattice. The monodisperse particles may have different optical properties based on their composition, their size, and/or their morphology (or shape). Also disclosed is a combination of at least two types of monodisperse particles, where each type is a plurality of monodisperse particles having a single pure crystalline phase of a rare earth-containing lattice, a uniform three-dimensional size, and a uniform polyhedral morphology; and where the types of monodisperse particles differ from one another by composition, by size, or by morphology. In a preferred embodiment, the types of monodisperse particles have the same composition but different morphologies. Methods of making and methods of using the monodisperse particles are disclosed.
