LaMO3 (M = Mg, Ti, Fe) perovskite type oxides: Preparation, characterization and catalytic properties in methane deep oxidation
Two new series of perovskite-type oxides LaMO3 (M = Mg, Ti, Fe) with different ratio Mg/Fe (MF) and Ti/Fe (TF) in the B cation site were prepared by annealing the precursor, obtained by the mechanochemical activation (MCA) ...
Synthesis of BaTiO3 from a mechanically activated BaCO 3-TiO2 system
(Belgrade : International Institute for the Science of Sintering, 2008)
In this article the solid state reaction of BaTiO3 formation from a mechanically activated BaCO3-TiO2 system has been investigated. An equimolar mixture of BaCO3 and TiO2 powders was activated in a planetary ball mill in ...
Crystal structure of hydroxyapatite nanorods synthesized by sonochemical homogeneous precipitation
(Crystal Growth and Design, 2008)
Using a homogeneous precipitation method in an ultrasound field, we synthesized nanosized, platelike hydroxyapatite (HAp). The internal structure of these platelike formations consists of specifically oriented and laterally ...
Far infrared spectroscopy of Pb0.85Sn0.15Te alloy doped with Ni
(Carl Hanser Verlag, 2008)
Far infrared reflectivity spectra of single crystal Pb0.85Sn0.15Te 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 ...
Morphology investigation of mechanically activated ZnO-SnO2 system
Powder mixtures of zinc oxide and tin oxide in the molar ratio, ZnO:SnO2 = 2:1, were mechanically activated in a planetary ball mill in the time intervals of 0-160 min. The adsorption-desorption isotherms, specific surface ...
