The present study is devoted to the extraction of rare-earth metals (REMs) from a high-silica ore found in one of the deposits in Kazakhstan. The ore was processed in a mixture with sulfuric acid at 200°C (sulphatization) and subsequently followed by water leaching of the sulphate product (sinter), REMs were extracted into the solution. Precipitation of the REMs-containing hydrate product from the sulfate solution was carried out with sodium hydroxide. In order to obtain the REMs-containing nitrate solution, the precipitate was dissolved in nitric acid. REMs solvent extraction from nitrate solutions was carried out with tributyl phosphate (TBP). 相似文献

Solid solutions (alloys) with a Cd concentration of 50.3–76.3 at % were synthesized for the first time in the form of coatings by ion–plasma sputtering and codeposition of ultrafine W and Cd particles. When coatings were formed by tungsten and cadmium nanolayers, the components dissolved mutually to produce solid solutions of one metal in the other. A solid solution of cadmium in tungsten was synthesized at Cd concentrations up to 60.9 at %. At a cadmium concentration of 68.6 at % in the coating, the crystalline structure of cadmium with an admixture of amorphous tungsten was produced. At 800°C, tungsten evaporated from tungsten–cadmium coatings to form porous tungsten. The results of examination of materials fabricated on the basis of porous tungsten are planned to be used in practice. 相似文献

A new sample of triple oxides—barium–thulium bismuthate Ba2TmBiO6 with perovskite structure—has been synthesized by ceramic technology. The unit cell parameters of the sample and the coefficients of thermal expansion have been determined by the method of X‐ray analysis. Thermal properties of the sample have been studied by DTA over the temperature range of 293–1473 K. The heat capacity of the compound has been measured over the range of 5–320 K by vacuum adiabatic calorimetry. Thermodynamic functions of the compound have been determined based on the heat capacity data. 相似文献
