Electrochemical determination of Gibbs free energy of formation of magnesium ferrite

引用

Journal of University of Science and Technology Beijing 2007年第4期14卷 361-364页

作者： Ling Wang Huizhu Zhou Yanruo Hong Girish m kale School of Chemical Engineering and Biotechnology Hebei Polytechnic University Tangshan 063009 China materials Science and Engineering School University of Science and Technology Beijing Beijing 100083 China School of Process Environmental and Materials Engineering Department of Mining and Mineral Engineering University of Leeds Leeds LS2 9IT UK

The standard Gibbs free energy of formation of magnesium ferrite was determined by means of two types of solid state electrochemical cells： one using mgZr4（PO4）6 （mZP） as the solid electrolyte and the other using CaF2 as the solid electrolyte. The first cell was operated in the range of 950 to 1100 K. The second cell was operated in the range of 1125 to 1200 K. The reversibility of the cell EmFs was confirmed by microcoulometric titration. The Gibbs energy changes of magnesium ferrite relative to component oxides were calculated based on EmF measurements and are given by following expressions, respectively： AG1 = -3579-15 T （J/mol） and AGⅡ =6258-24.3 T （J/mol）. The results obtained from two different cells are consistent with each other. The results also are in agreement with Rao＇ s and Tretjakov＇s data in the measured temperature range. When the Gibbs free energies of formation of mgO and Fe203 were substituted in the reaction, the Gibbs free energies of formation of mgFe204 was obtained in two temperature ranges and the for mations are shown as follows： AG 1Formation =-1427394＋360.5 T （J/mol） and AGⅡ Formition =-1417557＋351.2 T （J/mol）.

Effect of rare earth oxides on the properties of bio-soluble alkaline earth silicate fibers

引用

Journal of Rare Earths 2016年第2期34卷 203-207页

作者：王玺堂刘浩王周福马妍 Girish m.kale The State Key Laboratory of Refractories and metallurgy Wuhan University of Science and Technology Institute for materials Research School of Process Environmental and Materials Engineering University of Leeds

Using natural mineral wollastonite, talc and quartz sands as raw materials, rare earth oxides (La2O3, Nd2O3 and Y2O3) as additives, the bio-soluble alkaline earth silicate fibers were prepared by melting and blowing process. The viscosity of the molten ma-terials, bio-solubility and crystallization behavior of the fiber were investigated. The results indicated that the fiber drawing tempera-ture range could be broadened since the slope of the temperature-viscosity curve decreased with adding rare earth oxide. The addition of rare earth oxide was beneficial to the increase of crystallization temperature by strengthening the network structure of the fiber. The existence of rare earth oxide in the fibers would reduce the solubility of the fibers, which still belonged to bio-soluble fibers.

Herein, we report visible light active mesoporous cadmium bismuth niobate（CBN） nanospheres as a photocatalyst for hydrogen（H） generation from copious hydrogen sulfide（HS）. CBN has been synthesized by solid state reaction（SSR） and also using combustion method（Cm） at relatively lower *** as-synthesized materials were characterized using different techniques. X-ray diffraction analysis shows the formation of single phase orthorhombic CBN. Field emission scanning electron microscopy and high resolution-transmission electron microscopy showed the particle size in the range of.5–1 μm for CBN obtained by SSR and 50–70 nm size nanospheres using Cm, respectively. Interestingly, nanospheres of size 50–70 nm self assembled with 5–7 nm nanoparticles were observed in case of CBN prepared by *** optical properties were studied using UV–visible diffuse reflectance spectroscopy and showed band gap around.0 eV for SSR and 3.1 eV for Cm. The slight shift in band gap of Cm is due to nanocrystalline nature of material. Considering the band gap in visible region, the photocatalytic activity of CBN for hydrogen production from HS has been performed under visible light. CBN prepared by Cm has shown utmost hydrogen evolution i.e. 6912 μmol/h/0.5 g which is much higher than CBN prepared using *** enhanced photocatalytic property can be attributed to the smaller particle size, crystalline nature,high surface area and mesoporous structure of CBN prepared by combustion method. The catalyst was found to be stable, active and can be utilized for water splitting.

Ni-Cu-Zn ferrites with general formula Ni0.5Zn0.5-x/2Cux/2Fe2O4 (with x = 0.3, 0.4, 0.5 and 0.6) have been synthesized using oxalate precursor method with different precursor reaction temperatures in the range 10℃ to 70℃. The Curie temperatures obtained using AC susceptibility measurements are found to be in the range 150℃ to 350℃, the measurements also show single domain structure for all the samples except few compositions obtained at 35℃ precursor reaction temperature, show a multi-domain behaviour. The saturation magnetization is found to be in the range 20 to 51 emu/gm, while the magnetic moment is found to be in the range 0.63 to 1.5 μB. The hysteresis losses were found to be maximum for the samples obtained at precursor reaction temperature of 35℃. The grain size is found to be in the range 0.4 to 2.0 μm.
