Photoacoustic spectroscopy investigation of sintered zinc-tin-oxide ceramics
(Savez hemijskih inženjera, Beograd, 2007)
In this paper the changes that occured in differently activated ZnO-SnO(2) and sintered samples were investigated using photoacoustic spectroscopy. ZnO and SnO(2) powders, mixed in the molar ratio 2:1, were mechanically ...
Correlation between densification rate and microstructure evolution of mechanically activated BaTiO3
(Taylor & Francis Ltd, Abingdon, 2005)
Increasing demands on the quality of electronic ceramics requires a well-controlled correlation between particle morphology and processing conditions. Since mechanical activation is one of the methods for modification of ...
Application of the master sintering curve theory to non-isothermal sintering of BaTiO3 ceramics
(6th Conference of the Yugoslav Materials Research Society, YUCOMAT VI: Current Research in Advanced Materials and Processes, 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 ...
DPR analysis of microstructural evolution of ZnO ceramics
(Trans Tech Publications Ltd, Durnten-Zurich, 2004)
It is well known that, due to their specific properties, ZnO - based materials are frequently used in electrotechnics and electronics. Since these properties are very Much dependent on the microstructural state of material ...
SEM investigation of domain structure in (Ba,Ca,Pb)TiO3
(Elsevier Sci Ltd, Oxford, 1999)
In the present paper the microstructure and domain structure in modified BaTiO3 with Pb and Ca as additives have been investigated using SEM technique. The (Ba,Pb)TiO3 and (Ba,Ca,Pb)TiO3 ceramics show a slight difference ...
The effect of mechanical activation on synthesis and properties of MgAl2O4 ceramics
(Societa ceramica italianaPolitecnico di Torino, 2019)
Magnesium aluminate, MgAl2O4, and other alumina-based spinels are refractory ceramics with high hardness and resistance to chemical attack while also being possible microwave dielectrics. Pure MgAl2O4 can be optically ...
Influence of mechanochemical activation on sintering of cordierite ceramics with the presence of Bi2O3 as a functional additive
(Belgrade : Materials Research Society of Serbia, 2011)
According to its exceptional electrical characteristics, such as low temperature expansion coefficient, low dielectric constant and good mechanical properties, cordierite, 2MgO⋅2Al2O3⋅5SiO2, represents very attractive ...
Structural characterization and electrical properties of sintered magnesium-titanate ceramics
(Belgrade : Materials Research Society of Serbia, 2012)
In this article the influence of ball milling process on structure of MgO-TiO2 system, along with its influence on electrical properties of post-sintering samples, were investigated. Mixtures of MgO-TiO2 powders were ...
Synthesis and Characterization of Multifferoics 16%(Fe2O3)4%(BaCO3)80%(BaTiO3)
(Belgrade : Serbian Ceramic Society, 2017)
The initial powder (16 % Fe2O3, 4 % BaCO3, 80 % BaTiO3) was mechanically activated in a planetary mill for 20, 80, 120, 160, 200 and 220 minutes in air. Modified Faraday method was used to perform magnetization measurements ...
Electrical and mechanical properties of alumina doped with transition metal oxides sintered at 1400°C
(Societa ceramica italianaPolitecnico di Torino, 2019)
Corundum (alpha-alumina) is one of the most exploited materials in ceramic industry due to its good physico-chemical properties, mechanical properties, and, importantly, due to its low cost. Advantageous properties, such ...
