. The Raman results indicate that the catalyst persists pure fluorite cubic phases until the molar ratio of Mn exceeds 0.3, therefore MnOx particles form and impede the contact of the active site......
contribute towards the pseudocapacitive energy storage.Oxygen intercalation was exploited for the first time in fluorite crystals for fast energy storage and a specific capacitance value as high as 1099 F/g......
pressing technique.With increment excess contents of Sm2O3 and ZrO2 from 0 to 10wt%,the phase composition of the products is a mixed phase of pyrochlore structure and defective fluorite structure by X-ray......
less than 2 mm in size, were filled dominantly with fluorite accompanied by garnet, cassiterite, albite and white mica. These infilling minerals were crystallized late at the magmatic-hydrothermal... is characterized by abundant fluorite, and that the fluorides or fluorine complexes are the important forms that transport tin in fluids at this stage. In case the cavities are connected by tectonic fractures......
Round Top Mountain rhyolite(Texas, USA), a massive, unique Y-bearing-fluorite-hosted heavy rare earth element(HREE) depositPINGITORE Nicholas1,CLAGUE Juan11. Department of Geological Sciences... proportions. REE-bearing minerals reported in the deposit included bastn site-Ce, Y-bearing fluorite, xenotime-Y, zircon, aeschynite-Ce, a Ca-Th-Pb fluoride, and possibly ancylite-La and cerianite-Ce......

own hydrothermal center with a clear regular zone mineralization distribution of W-Sn,Pb-Zn and fluorite deposits. Homogenization temperature of fluid inclusions is consistent with mineralization zone in term of spatial distribution. The temperature decreases continuously from W-Sn deposits (215-384 ℃) to fluorite deposits (136-194 ℃). Two ore-forming systems show high concentrations of LREE......
Rare Earth Doping Effects on Properties of Ceria-Zirconia Solid Solution胡玉才,殷平,梁涛,姜玮,刘冰摘 要:<正>Ce0.6Zr0.3RE0.1O2(RE = Y, La, Pr, Tb)solid solutions were prepared by co-precipitation technique and characterized by a series of methods. XRD and FT-Raman results show that Ce0.6Zr0.3RE0.1O2 has cubic fluorite structure. The different dopant ion radii......
solution with a fluorite structure is obtained by the diffusion of trivalent Pr enters CeO2 crystal lattice during the synthesis process. The pigments prepared by low-temperature combustion synthesis (LCS......
Wet Air Oxidation of Organic Wastewater Catalyzed by Doped Ceria应跃芳,王月娟,何军,罗孟飞摘 要:The catalytic wet air oxidation (CWAO) of H acid and phenol was investigated in the presence of Cu or Fe doped CeO2 solid solutions, which were obtained by sol-gel method. The experiment results showed that the incorporation of Cu or Fe into the fluorite lattice of CeO2......
