Microstructural evolution and electric properties of mechanically activated BaTiO3 ceramics
(Oxford : Elsevier Sci Ltd, 2007)
Ceramic materials with a perovskite related structures such as non-doped and doped barium titanate ceramics are attracting much interest for their application as capacitor dielectrics, resistors, thermal sensors, etc. Since ...
The effect of ball milling on properties of sintered manganese-doped alumina
(Elsevier, 2019)
Alumina-based compounds have many technological applications and attract great attention even after decades of investigation, due to their good chemical, electrical, and mechanical properties. A mixture of several alumina ...
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
(Elsevier, 2009)
The aim of this work was an investigation of structural and electrical properties of sintered zinc-titanate ceramics obtained by mechanical activation. Mixtures of ZnO and TiO2 were mechanically activated in a planetary ...
Effects of mechanical-activation and TiO2 addition on the behavior of two-step sintered steatite ceramics
(Elsevier, 2019)
Steatite, as ceramic with composition predominantly resting on magnesium silicate, was produced from economic resources – talc, aluminosilicate clays, and either BaCO3 or feldspar as flux. Titanium dioxide was a doping ...
Mg/Cu co-substituted hydroxyapatite – Biocompatibility, mechanical properties and antimicrobial activity
(Elsevier, 2019)
The aim of this study was to improve the mechanical properties and to optimize antimicrobial activity of hydroxyapatite (HAP) by simultaneous doping with Mg and Cu ions in order to obtain material that would be able to ...
A new neural network approach to density calculation on ceramic materials
(World Scientific Pub Co Pte Ltd, 2021)
The materials’ consolidation, especially ceramics, is very important in advanced research development and industrial technologies. Science of sintering with all incoming novelties is the base of all these processes. A very ...
Niobium doping effect on BaTiO3 structure and dielectric properties
(Elsevier, 2020)
The effect of Nb on the microstructure and dielectric properties of BaTiO3 ceramics was investigated. The Nb/Mn–BaTiO3 ceramics were prepared using a conventional solid-state method. The concentration of Nb varied from 0.1 ...
Influence of mechanochemical activation on the sintering of cordierite ceramics in the presence of Bi2O3 as a functional additive
(Elsevier, 2012)
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 ...
Nanostructured constituents of ZnO-based varistors prepared by mechanical attrition
(Elsevier, 1994)
Nanostructured powders, with crystallite size of ZnO, spinel and γ-Bi2O3 phases below 100 nm, were obtained by the mechanical attrition of ZnO varistor powders prepared by method of directed synthesis of the constituent ...
