Preparation of ZrO2 and ZrO2/SiC powders by carbothermal reduction of ZrSiO4
(Journal of Alloys and Compounds, 2011)
This paper is dealing with the synthesis of zirconia/silicon carbide (ZrO2/SiC) and ZrO2 powders obtained by carbothermal reduction of natural mineral zircon (ZrSiO4). For the first time, the influence of carbon to ZrSiO4 ...
Structural and magnetic properties of hydrothermally synthesized beta-MnO2 and alpha-KxMnO2 nanorods
(Journal of Alloys and Compounds, 2016)
Hydrothermal synthesis was applied for obtaining different manganese dioxide polymorphs whose morphology, structure and magnetic properties were thoroughly investigated. Variations in the synthesis pathways lead to the ...
Identification of phase components in Zr-Ni and Hf-Ni intermetallic compounds; investigations by perturbed angular correlation spectroscopy and first principles calculations
(Journal of Alloys and Compounds, 2017)
Time-differential perturbed angular correlation (TDPAC) measurements have been carried out in stoichiometric ZrNi3 and HfNi3 intermetallic compounds using Ta-181 probe in the temperature range 77-1073 K considering the ...
Kinetic study of isothermal crystallization process of Gd2Ti2O7 precursors powder prepared through the Pechini synthetic approach
(Journal of Physics and Chemistry of Solids, 2015)
Crystallization process of Gd2Ti2O7 precursors powder prepared by Pechini-type polymerized complex route has been studied under isothermal experimental conditions in an air atmosphere. It was found that the crystallization ...
Europium-doped nanocrystalline Y2O3 - La2O3 solid solutions with bixbyite structure
(Journal of Physics and Chemistry of Solids, 2014)
Nanocrystals of Y2O3 and La2O3 solid solutions were synthesized with a cubic bixbyite structure containing La2O3 content of up to 50 mol%. This is comparatively higher than that in bulk materials of the same structure, ...
Synthesis and characterization of high-pressure and high-temperature sphene (CaTiSiO5)
(Physics and Chemistry of Minerals, 2014)
Sphene (CaTiSiO5), a calcium titanosilicate ceramic has been prepared from a powder mixture of CaCO3, TiO2 and SiO2 using vibro-milling for homogenization and activation of precursors. During the high-pressure and ...
Site preference of Hf dopant in Ni3Al alloys: A perturbed angular correlation study
(Journal of Alloys and Compounds, 2015)
Perturbed angular correlation measurements of the hyperfine interactions of the Ta-181 probe in the polycrystalline intermetallic Ni3Al doped with 0.5 and 5 at.% Hf were performed in the temperature range 78-1230 K. The ...
Raman spectroscopy of ZnS quantum dots
(Journal of Alloys and Compounds, 2015)
ZnS nanoparticles were synthesized mechanochemically by high-energy milling. In order to investigate influence off milling time to sample properties, samples were produced in three different milling times (5 min, 10 min ...
