Densification, Microstructure, and Electrical Properties of BaTiO3 (BT) Ceramics Prepared from Ultrasonically De-Agglomerated BT Powders
(Taylor & Francis, 2009)
In this study, a correlation between densification, microstructure, and electrical properties of BaTiO3 (BT) ceramics prepared from ultrasonically de-agglomerated BT powders has been analyzed. BT powders with the same ...
Structural and Electrical Properties of Sintered Zinc-titanate Ceramics
Poster presented at the ELECTROCERAMICS X, June 18-22, 2006, Toledo, Spain
Fractal corrections of BaTiO3-ceramic sintering parameters
(Belgrade : International Institute for the Science of Sintering, 2014)
Morphology of ceramics grains and pores as well as Brownian character of particle dynamics inside ceramics specimen contributes to better understanding of the sintering process. BaTiO3-ceramics, studied in this paper, has ...
Humidity sensing potential of Fe2TiO5—pseudobrookite
(Springer US, 2018)
Bulk samples of pseudobrookite with an orthorhombic crystal structure were prepared by sintering a mixture of starting hematite and anatase nano powders in the weight ratio 60:40 at three different sintering temperatures ...
Structural and electrical properties of sintered Fe2O3/TiO2 nanopowder mixtures
Starting nanopowders of TiO2 (anatase 99.7%) and α-Fe2O3 (hematite) were mixed in the weight ratios 60:40 and 40:60. Green samples were sintered in the temperature range 750–1250 °C in air. Structural, morphological and ...
Microstructure and dielectric properties of Dy/Mn doped BaTiO3 ceramics
Dy/Mn doped BaTiO3 with different Dy2O3 contents, ranging from 0.1 to 5.0 at% Dy, were investigated regarding their microstructural and dielectric characteristics. The content of 0.05 at% Mn was constant in all the ...
The Influence of Sintering Parameters and Subsequent Thermal Treatment on U-I Characteristics and Degradation of ZnO Varistors
(New York; London : Plenum Press, 1987)
The fabrication of varistor ceramics, characterized by stable electrical properties, was considered on the basis of sintering parameters and subsequent thermal treatment. The process of accelerated degradation of electrical ...
The influence of mechanical activation on the electrical properties of Ba0.77Sr0.23TiO3 ceramics
Ferroelectric barium strontium titanate (Ba0.77Sr0.23TiO3), BST, was prepared by solid-state reactions using as the starting compounds powder of barium carbonate (BaCO3), strontium carbonate (SrCO3) and titanium dioxide ...
Influence of mechanochemical activation on the sintering of cordierite ceramics in the presence of Bi2O3 as a functional additive
Due to its outstanding electrical characteristics, such as the low temperature expansion coefficient, low dielectric constant and good mechanical properties, cordierite, 2MgO⋅2Al2O3⋅ 5SiO2, is a very attractive high-temperature ...
The fractal nature approach in ceramics materials and discrete field simulation
In this paper, we present experimental data of static fractals and compare the results with theoretical analysis obtained using dynamic particle simulation. The fractal simulator presented in this manuscript is pioneer ...
