Properties of LiMn2O4 powders obtained by ultrasonic spray pyrolysis
(Progress in Advanced Materials and Processes, 5th Conference of the Yugoslav-Materials-Research-Society (Yu-MRS 2003), Sep 15-19, 2003, Herceg Novi, Yugoslavia, 2004)
LiMn2O4 powders were synthesized by ultrasonic spray pyrolysis. By varying the cooling conditions. two samples of powders were obtained: quenched in water (Q) and spontaneously cooled to room temperature (SC). The crystal ...
Far infrared spectroscopy of Pb0.85Sn0.15Te alloy doped with Ni
(Carl Hanser Verlag, 2008)
Far infrared reflectivity spectra of single crystal Pb 0.85Sn0.15Te doped with Ni were measured in the temperature range between 10 K and 300 K. Analysis of the experimental spectra was made using a fitting procedure based ...
Formation of magnesium titanates
The paper examines the phase formation in the mechanochemical treatment and subsequent annealing of TiO 2 and MgO mixtures. It is established that the MgTiO 3 phase forms during annealing of the above powder mixtures at ...
Influence of ZnO specific surface area on its sintering kinetics
(Киев : Украинское материаловедческое общество; Националная академия наук Украины; националниый технический университет Украины „Киевский политехнический институт“, 2008)
Paper presented at the conference Материаловедение тугоплавких соединений: достижения и проблемы, Киев, Украина, 27-29 мая 2008.
Reduction of the specific surface area of porous ZnO during sintering
(Čačak : Technical Faculty, 2007)
In this paper reduction of the specifice surface area of porous ZnO during sintering was analyzed. ZnO was sintered at temperatures from 673K to 1173K. Reduction of the specific surface area was observed as a function of ...
Far infrared study of local impurity modes of Gd doped PbTe
Single crystal samples of lead telluride doped with Gd were grown using the Bridgman method. Far infrared reflectivity spectra in the temperature range from 10 K to 300 K were measured. The experimental diagrams were ...
Injectable polydimethylsiloxane-hydroxyapatite composite cement
(Bio-medical Materials and Engineering, 2003)
An injectable polydimethylsiloxane/hydroxyapatite (PDMS/HAp) composite cement was synthesised using linear PDMS and HAp (particles of about 100 nm in size) of different mass fractions. The effect of HAp mass fraction (5-60 ...
Citrate-based zinc-polyaniline secondary cell: Part I: Optimization of the citrate/chloride electrolyte
Electrochemical behavior of zinc and thin polyaniline (PANI) electrodes in citrate/chloride-contained electrolyte has been investigated by the means of electrolyte composition optimization. Electrolyte contained 0.8 M ...
Structural analysis of Zn2TiO4 doped with MgO
The starting mixtures of ZnO, TiO2, and MgO (0, 1.25, and 2.5 wt.%) powders are mechanically activated in a high-energy planetary mill for 15 min and then sintered between 800 and 1100°C for 2 h. The influence of MgO ...
Synthesis and characterization of LiFePO4/C composite obtained by sonochemical method
(Solid State Ionics, 2008)
Lithium iron phosphate has become of great interest as storage cathode for the next generation of rechargeable lithium batteries. Olivine structure LiFePO4/C composite powder was prepared by ultrasound assisted synthesis. ...
