Antiferromagnetism and heat capacity of NaCo2-xCuxO4 ceramics
(Elsevier Sci Ltd, Oxford, 2017)
Polycrystalline samples of NaCo2-xCuxO4 (x=0, 0.01, 0.03 and 0.05) were synthesized in two different ways: 1) by a mechanochemically assisted solid-state reaction method (MASSR) and 2) by a citric acid complex method (CAC). ...
Sintering and electrical properties of Ce1-xBixO2-delta solid solution
(Elsevier Science Sa, Lausanne, 2014)
Solid solution Ce1-xBixO2-delta nanopowders with the composition of x = 0.1-0.5 were synthesized by using Self Propagating Room Temperature procedure (SPRT). The results obtained by XRPD show that synthesized samples were ...
Dielectric and ferroelectric properties of BST ceramics obtained by a hydrothermally assisted complex polymerization method
(Elsevier Sci Ltd, Oxford, 2015)
Ba0.8Sr0.2TiO3 (BST) powder, obtained by a hydrothermal treatment of precursor solution previously prepared by a complex polymerization method (HT-CPM), was uniaxially pressed and sintered at 1280 degrees C for 1-32 h. The ...
Synthesis of Barium-zinc-titanate Ceramics
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2012)
Mixtures of BaCO3, ZnO and TiO2 powders, with molar ratio of 1:2:4, were mechanically activated for 20, 40 and minutes in a planetary ball mill. The resulting powders were compacted into pellets and isothermally sintered ...
Studies on structural, morphological and electrical properties of Ce1-xErxO2-delta (x=0.05-0.20) as solid electrolyte for IT - SOFC
(Elsevier Science Sa, Lausanne, 2015)
A series of four different powders ceria doped Ce1-xErxO2-delta (0.05 lt = x lt = 0.20) were synthesized by applying self-propagating reaction at room temperature (SPRT method). SPRT procedure is based on the self-propagating ...
Influence of Nitrogen and Air Atmosphere During Thermal Treatment on Micro and Nano Sized Powders and Sintered TiO2 Specimens
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2014)
The influence of air and nitrogen atmosphere during heating on TiO2 nano and micro sized powders as well as sintered polycrystalline specimens was analyzed. Sintering of TiO2 nano and micro powders in air atmosphere was ...
Magnetic properties of doped LaMnO3 ceramics obtained by a polymerizable complex method
(Springer, Dordrecht, 2010)
Substituted lanthanum manganites with the general formula A(1-x) B (x) MnO3 (A = La, B = Ca, SraEuro broken vertical bar) have attracted a lot of attention due to their exceptional electric and magnetic properties. In this ...
Effect of preparation route on the microstructure and electrical conductivity of co-doped ceria
(Elsevier Sci Ltd, Oxford, 2013)
Dense Ce0.8Sm0.1Gd0.1O2-delta electrolytes were fabricated by sintering of CeO2 solid solutions which were prepared from metal nitrates and NaOH using self propagating room temperature synthesis (SPRT). Three different ...
