Effect of consolidation parameters on structural, microstructural and electrical properties of magnesium titanate ceramics
(Elsevier, 2016)
The aim of this study is to explore the influence of the processing route on the structural and physical properties of bulk MgTiO3 ceramics. Commercially available MgO and TiO2 powders were mechanically activated in a ...
The effect of mechanical activation on synthesis and properties of MgAl2O4 ceramics
(Elsevier, 2019)
Magnesium aluminate, MgAl2O4 and other alumina-based spinels are ceramics with high hardness, high melting point and mechanical strenght. Spinels can also be used as dielectrics in microwave applications. The goal of this ...
Densification rate and phase structure changes during sintering of zinc titanate ceramics
(Elsevier, 2009)
Densification rate and phase structure changes during sintering of nanosized ZnTiO3 were studied. Sintering was performed in a dilatometer in two regimes: the first to 900 °C (heating rates 5, 10 and 15 °C/min) and the ...
Inert atmosphere processing of hydroxyapatite in the presence of lithium iron phosphate
(Journal of the European Ceramic Society, 2018)
The present study describes sintering behaviour of hydroxyapatite (HAp) upon addition of lithium iron phosphate (LFP) (1-10 wt.%) system in inert (Ar) atmosphere. The interaction between materials and melting of LFP ...
The contribution of fractal nature to BaTiO3-ceramics microstructure analysis
(Elsevier, 2012)
The structure of BaTiO3 based materials can be controlled by using different technological parameters and different additives. In this paper, microstructure and dielectrical properties of Er2O3 doped BaTiO3-ceramics, ...
Microstructure and mechanical properties of disperse Ni-Co alloys electrodeposited on Cu substrates
(Elsevier, 2010)
The nickel and cobalt disperse alloy deposits of five different compositions were obtained by electrodeposition on Cu substrates in the galvanostatic regime from an ammonium sulfate-chloride solution. The effect of cathodic ...
Compressive strength and microstructure of ordinary cured and autoclaved cement-based composites with mechanically activated kaolins
(Elsevier, 2018)
The effects of two different mechanically activated kaolins, AKV (61% kaolinite, 14% quartz and 16% mica) and AKG (51.6% kaolinite and 40.6% quartz) on the compressive strength of cement composites and microstructure of ...
Microstructure and dielectric properties of Dy/Mn doped BaTiO3 ceramics
(Elsevier, 2014)
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 ...
Peculiarities in sintering behavior of Ca-deficient hydroxyapatite nanopowders
(Elsevier, 2012)
We report unusual sintering behavior of Ca-deficient hydroxyapatite processed with different heating rates; particularly, faster heating resulted in higher densification. We hypothesize that faster heating delays formation ...
Macro and Micro-Scale Features of Thermoelectric PbTe (Br, Na) Systems: Micro-FTIR Spectroscopy, Micro-Seebeck Measurements, and SEM/EDX Observations
(Springer, 2014)
In this work, n-type and p-type PbTe doped with Br and Na, respectively, were thoroughly examined to determine the effect of the dopant on microstructure. Macro and micro homogeneity of the samples were studied by means ...
