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 ...
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, ...
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 ...
The use of various dicarboxylic acids as a carbon source for the preparation of LiFePO4/C composite
(Elsevier, 2015)
Olivine-type LiFePO4 composite powders with carbon were synthesized by freeze drying and subsequent thermal annealing. The main purpose of the research is to explore how various dicarboxylic acids as carbon sources influence ...
Dry-pressed anodized titania nanotube/CH3NH3PbI3 single crystal heterojunctions: The beneficial role of N doping
(Elsevier, 2019)
Highly ordered, anodically grown TiO 2 nanotubes on titanium supports were annealed in ammonia atmosphere in order to incorporate nitrogen doping (≤2 at.%) in the titanium oxide lattice. FESEM micrographs revealed nanotubes ...
Fractal approach to BaTiO3-ceramics micro-impedances
(Elsevier, 2015)
A new approach, based on fractal geometry and correlation between microstructure-nanostructure and rare-earth properties and other additives doped BaTiO3-ceramics and electronics properties, is applied. The grain contacts ...
Designing, fabrication and characterization of nanostructured functionally graded HAp/BCP ceramics
(Elsevier, 2015)
Nanostructured calcium phosphate functionally graded materials (FGMs) with simultaneous gradients of density, phase composition, and mechanical properties were fabricated by consecutive uniaxial pressing of stoichiometric ...
Optimization of bentonite clay mechano-chemical activation using artificial neural network modeling
(Elsevier, 2017)
The properties of seven montmorillonite-rich bentonites of different geological origin were investigated prior and subsequent to mechano-chemical processing in an ultra-centrifugal mill. The objective of the experiment was ...
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 ...
Influence of ageing of milled clay and its composite with TiO2on the heavy metal adsorption characteristics
(Elsevier, 2015)
The aim of the present study was to investigate the effect of ageing of mechanochemically synthesized clay and its TiO2composite on the simultaneous removal of Pb(II), Cd(II), Cu(II) and Zn(II) ions from acidic aqueous ...
