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 ...
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 ...
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 ...
Influence of mechanical activation on functional properties of barium hexaferrite ceramics
(Elsevier, 2018)
Barium hexaferrite ceramics were prepared using mechanically activated mixtures of iron and barium titanate. The 60:40 mass% Fe:BaTiO3 powder mixtures were mechanically activated for different times (100–240 min) and ...
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 ...
Influence of different pore-forming agents on wollastonite microstructures and adsorption capacities
(Elsevier, 2017)
In this study, porous macro- and micro-cellular wollastonite-based ceramics was synthesized. A ceramic precursor, methylhydrocyclosiloxane, together with micro-sized CaCO3, was used as a starting material. After 20 min of ...
Artificial fly ash based aggregates properties influence on lightweight concrete performances
(Elsevier, 2015)
The effect of the application of pelletized fly ash based aggregates obtained through different processing techniques on the behavior of lightweight concretes was analyzed. Experimental program implied production of four ...
