摘要： L'invention a pour objet un procédé de préparation de fluorures doubles d'uranium et d'ammonium ou d'un métal alcalin ou alcalino-terreux.
Le procédé selon l'invention se caractérise en ce qu'il comporte les étapes suivantes :
- la réduction catalytique par l'hydrogène, en présence d'ions H⁺, d'une solution d'un sel d'uranium (VI) soluble en une solution d'un sel d'uranium (IV) soluble,
- la réaction du sel d'uranium (IV) obtenu à l'étape précédente avec des ions fluorures, en présence d'ions ammonium, alcalin ou alcalino-terreux, pour obtenir la précipitation du fluorure double d'uranium et d'ammonium ou d'un métal alcalin ou alcalino-terreux,
- la récupération du fluorure double sous forme de précipité.摘要翻译： 本发明涉及一种制备铀和铵或碱金属或碱土金属的双氟化物的方法。 该方法的特征在于其包括以下阶段： - 在H +离子存在下，将可溶性铀（VI）盐溶液中的氢气还原成可溶性铀（IV）溶液， 盐， - 在前一阶段获得的铀（Ⅳ）盐与铵离子，碱金属或碱土金属离子的存在下，与氟离子反应，以获得铀和铵的双氟化物或铵或 碱金属或碱土金属， - 以沉淀形式回收双重氟化物。 C

摘要： This invention relates to material compositions, a manufacturing method for these materials and a manufacturing method for ceramic bodies, to be used as targets in physical vapour deposition techniques of p-type transparent conductive films. There is disclosed a method for manufacturing a pelletized oxide material Mx Sr1−xCu2-+aO2+b, wherein −0.2≦̸a≦̸0.2, −0.2≦̸b≦̸0.2, and M is either one or more of the group of bivalent elements consisting of Ba, Ra, Mg, Be, Mn, Zn, Pb, Fe, Cu, Co, Ni, Sn, Pd, Cd, Hg, Ca, Ti, V, Cr; with 0≦̸x≦̸0.2; comprising the steps of: —providing a precursor mixture having a given grain size distribution, and comprising stoichiometric quantities of Cu2O, Sr(OH)2.8H2O, and, when 0≦̸x≦̸0.2, M-hydroxide, —intimately mixing said precursor mixture so as to obtain a homogeneous mixture, and —sintering said homogeneous mixture at a temperature above 850° C. The oxide material Sr Cu2+aO2+b has a residual carbon content of less than 400 ppm, and a target having a density of at least 5.30 g/ml can be manufactured with it.

摘要： For the recovery of uranium from a solution in which the uranium has a valency (VI), a solution is formed containing ammonium (NH 4 + ), fluoride (F―) and sodium hydrosulfite (Na 2 S 2 0 4 ). This forms a precipitate (NaNH 4 UF 6 ), a previously unreported compound. It can be dissolved in an aqueous solution of aluminum nitrate nonahydrate, Al(NO 3 ) 3 . 9H 2 0. This produces uranyl nitrate hexahydrate, which can be extracted in solutions conventionally used for that purpose.
