The extraction separation of Sm3+ and Zn2+ was studied by using 1.5 mol/L P507-kerosene as organic phase and mixed solution of SmCl3 and ZnCl2 as feed liqiuid. Effects of concentration of NH4Cl, feed acidity, concentration of Zn2+ in the feed liuquid, organic saponification degree, phase ratio and mixing time on separation of Sm3+ and Zn2+ were investigated. The results show that the optimal process parameters of the extraction separation of Sm3+ and Zn2+ are organic saponification degree 0.54 mol/L, concentration of NH4Cl 3 mol/L in the feed liuquid, the feed acidity 0.15 mol/L, the phase ratio O/A more than 2.5:1 and the mixing time more than 4 minutes. The maximum separation factor of Sm3+ and Zn2+ βSm/Zn was 39.31. © 2017, Editorial Office of "Chinese Rare Earths". All right reserved.

The Sm0.5Sr0.5Co1-x CuxO3-δ powders were synthesized by a urea-nitrate combustion method. The formation process, crystal structure, micrograph and thermal expansion coefficient (TEC) of the as-synthesized samples were investigated by TG-DSC, XRD, SEM and dilatometer, respectively. The electrical conductivities of the samples were measured by four point electrodes method at 500~800°C in air. The results showed that the major phase of the as-synthesized powders was orthorhombic perovskite structure, whereas some impurity peaks existed in the samples. The conductivity of the samples with x<0.2 decreased with increasing temperature, while for the samples with x≥0.3, the electrical conductivity increased with temperature. The sample with x=0.2 exhibited the highest conductivity, which was 703.1 S·cm-1 at 500°C. The thermal expansion coefficients of Sm0.5Sr0.5Co1-x CuxO3-δ were decreased monotonously with Cu doping.

The saponifier was prepared by reusing the saponification wastewater from light rare earths extraction separation. The saponification wastewater was reused according to sodium chloride concentration and different trace rare earth ions in it and the requirement purity of light rare earth elements extraction separation. The results show that the discharge quantity of the wastewater was decreased and fresh water was saved and the concentration of sodium chloride in th wastewater was increased by resuing saponification wastewater. And the energy consumption was reduced in the concentration and crystallization of recycing sodium chloride, and the yield of rare earths was improved, and the consumption of organic was reduced. ©, 2015, Editorial Office of Chinese Rare Earths.

Ammonium hydrogen carbonate is taken as the precipitating agent to prepare Pr-N d carbonates from the raw material of Pr-Nd chloride solution. Pr-Nd oxides have been pre pared at different calcination temperature in the range of 800 °C-1500 °C. The oxides were c haracterized by XRD and XPS. Calcination temperature effects on the structure of Pr-Nd oxi des and the valence state of Pr in Pr-Nd oxides have been studied; Results showed that pra seodymium oxide full entered into the lattices of neodymium oxide. The crystal structure ch anged from cubic into hexagonal system with increasing calcination temperature.The valence of Pr in Pr-Nd binary oxides are Pr3+ and Pr4+. © (2011) Trans Tech Publications, Switzerland.

Yttrium oxide powder with large particle sizes and spherical shapes were prepared by precipitation with ammonium bicarbonate. The powders were characterizated by laser partical size analyzer, SEM and BET. Influence of reaction temperature, concentration of feed liquid, aging time and calcination temperature on morphology, particle size and specific surface area of yttrium oxide was studied. The optimum process conditions were that the reaction temperature of precipitation was 93°C, concentration of feed liquid was 40 g/L, aging time was 28 h, and calcination temperature was 1400°C. Yttrium oxide with medium diameter of 61.54 μm and acicular spherical morphology was obtained under the conditions.

Yellow pigments of Sm0.3 Ce0.66Mo0.04 O(1.85 + δ) were prepared by doping four mineralizers such as NaF, NaCl, H3BO3 and Na2HPO4 and changing calcination temperature. Their crystal structure were characterized by XRD. Their optical properties were analyzed by the CIE 1976 L* a* b* colorimetric scales and UV-vis reflectance spectroscopy. The results show that the yellow pigments belong to the cubic fluorite structure. The brilliant yellow pigment were prepared when the mineralizer was H3BO3. The reflection absorption edge was red shifted and the colour of pigment changed from yellowish to bright yellow as increasing calcination temperature. ©, 2014, Editorial Office of Chinese Rare Earths.

Sm0.3Ce(0.7-x)MoxO(1.85+δ) yellow pigments were prepared by solid-state synthesis method, which were obtained by doping molybdenum for substitution of Ce4+ in Sm0.3Ce0.7O1.85. Effects of Molybdenum doping amount on crystal structure of the pigments were investigated and the coloring mechanism of the pigments was analyzed. The results show that molybdenum doping has markedly changed the color of the pigments. The color of pigments changed from cream to yellow as molybdenum doping amount increased from x=0.00 to x=0.04. And the color changed from yellow to yellow green when x was adjusted from x=0.05 to x=0.07. When x=0.08, the color of pigments changed to gray. © (2013) Trans Tech Publications, Switzerland.

In this paper, the solubility of gadolinium in sodium carbonate and ammonium bicarbonate was studied. As a result, the solubility increased then decreased with reaction time. The solubility was improved by increasing carbonate concentration. With the increasing temperature, the solubility increased in sodium carbonate but decreased in ammonium bicarbonate solution. The solubility of gadolinium increased in anmmonium bicarbonate but decreased in sodium carbonate with addition of ammonium hydroxide.
