Influence of ZnO specific surface area on its sintering kinetics
The aim of this work is an investigation of isothermal sintering kinetics by observing the reduction of the specific surface area of ZnO. Zinc oxide powder is sintered isothermally in air for 5 to 120 min at temperatures ...
Precursor particle size as the key parameter for isothermal tuning of morphology from nanofibers to nanotubes in the Na2-xHxTi nO2n+1 system through hydrothermal alkali treatment of rutile mineral sand
(Washington : American Chemical Society, 2009)
Morphology control in the (Na,H)2TinO2n+1 system has been achieved by introducing particle size as the key parameter during hydrothermal synthesis. The process is applied for the synthesis of TiO2-based nanofibers and ...
Far infrared study of impurity local modes in Pr doped PbTe
Single crystal samples of lead telluride doped with Pr were produced using the Bridgman method. Far infrared spectra of the samples doped with 0.15 at%, 0.25 at% and 0.6 at% Pr are presented. The experimental data were ...

Surface analysis of bismuth titanate by Auger and X-ray photoelectron spectroscopy
The Auger and XPS technique has been used for investigation in the surface of bismuth titanate (Bi4Ti3O12) (BIT) ceramics obtained by reactive sintering from Bi2O3 and TiO2 oxides. All peaks characteristic for bismuth, ...
Influence of mechanical activation on structural and electrical properties of sintered MgTiO3 ceramics
(Belgrade : International Institute for the Science of Sintering, 2009)
The aim of this work was to analyze the influence of mechanical activation on the MgCO3-TiO2 system. Mixtures of MgCO3-TiO2 were mechanically activated for 15, 30, 60 and 120 minutes in a planetary ball mill and after that ...
Isothermal sintering of BZT ceramics
Starting mixtures of BaCO3 •ZnO and Ti02 were mechanically activated for 0,5, 10,20.40 and 80 minutes in a planetary ball mill. The powders obtained were sintered isothermally to temperatures between 1000 and 1300 °C. The ...
