Preparation and properties of BaTi1-xSnxO3 multilayered ceramics
(Journal of the European Ceramic Society, 2007)
BaTi1-xSnxO3 (BTS) powders, with x ranging from 0 to 0.15, were synthesized by solid-state reaction technique. The powders were pressed and sintered at 1370 degrees C. Obtained BTS ceramics were investigated by X-ray ...
Structural and Electrical Properties of Sintered Barium-Zinc-Titanate Ceramics
(Warsaw : Institute of Physics, Polish Academy of Science, 2011)
The aim of this work was an investigation of structural and electrical properties of sintered barium-zinc-titanate ceramics. Mixtures of BaCO3, ZnO and TiO2 were mechanically activated in a planetary ball mill up to 80 ...
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, ...
Microstructure changes caused by thermal etching of sintered ZnTiO3
Polishing and thermal etching was performed on ZnTiO3sintered ceramic. Two set of specimens were recorded, on higher 1200oC/1100oC sintered/etched, and lower 900oC/800oC sintered/etched. Phase composition, crystallite sizes ...
Densification of BTS Functionally Graded Materials during Sintering

Ho2O3 Additive Effects on BaTiO3 Ceramics Microstructure and Dielectric Properties
(Belgrade : International Institute for the Science of Sintering, 2012)
Doped BaTiO 3-ceramics is very interesting for their application as PTCR resistors, multilayer ceramic capacitors, thermal sensors etc. Ho doped BaTiO 3 ceramics, with different Ho 2O 3 content, ranging from 0.01 to 1.0 ...
Synthesis and dielectric properties of calcium copper titanate (CCTO) based ceramics
(Belgrade : Institute of Technical Sciences of SASA, 2010)
The perovskite CaCu3Ti4O12 (CCTO) powders with various oxide phase impurities were synthesized via citric gel combustion method. Influence of citric acid amount used for gel preparation was examined in order to lower CCTO ...

Structural analyses of sintered MT and BZT ceramics
(Belgrade : Serbian Society for Microscopy, 2010)
Development of dielectric materials is increasing with a rapid progress in mobile and satellite communications systems, where magnesium titanates find their place owing to good dielectric properties. Recently it has been ...
Influence of different bonding and fluxing agents on the sintering behavior and dielectric properties of steatite ceramic materials
The focus of the study was on providing insights into interconnections between sintering and development of the crystalline microstructure, and consequently variations in dielectric behavior of four steatites fabricated ...
