Microstructural properties of PZT thin films deposited on LaNIQ 3-coated substrates
(Trans Tech Publications Ltd, 2007)
The modified polymeric precursor method (Pechini method) was successfully used for the preparation of epitaxial and polycrystalline ferroelectric Pb(Zr0.52Ti0.48)O3 (PZT) thin films. Films were deposited on LaNiO3 (LNO) - ...
Mechanochemical synthesis of CaTiO3 from CaCO3-TiO2 mixture
(Trans Tech Publications Ltd, 2004)
The synthesis of calcium titanate, CaTiO3, was performed by mechanical activation and thermal treatment. Milling for up to 360 minutes in a planetary ball mill mechanically activated an equimolar mixture of CaCO3 and TiO2 ...
Electrical characterization of the grain-boundary region of SnO2 varistors
(Trans Tech Publications Ltd, 2006)
The effect of Co, Cr and Nb on the electrical properties of the grain boundaries of SnO2-based varistors was investigated. The powders were prepared by the method of evaporation and decomposition of solutions and suspensions. ...
Application of the master sintering curve theory to non-isothermal sintering of BaTiO3 ceramics
(Trans Tech Publications Ltd, 2005)
In this paper a practical approach to the analysis of sintering of BaTiO3 using the Master Sintering Curve concept has been presented. Non-isothermal sintering of high-purity non-doped BaTiO3 ceramics was monitored using ...
The influence of mechanical activation on the stoichiometry and defect structure of a sintered ZnO-Cr2O3 system
(Trans Tech Publications Ltd, 2004)
Mixtures of starting ZnO and Cr2O3 powders in equimolar quantities were mechanically activated by grinding using a high energy vibro-mill for 0, 40 and 80 minutes. Qualitative X-ray diffraction analysis made after sintering ...
