Nanostructured Fe2O3/TiO2 thick films: Analysis of structural and electronic properties
(Elsevier, 2015)
Thick films using starting nanopowders of TiO2 (anatase 99.7%) and α-Fe2O3 (hematite) mixed in the weight ratios 60:40 and 40:60 for thick film paste were fabricated by screen printing technology on an alumina substrate. ...
Assessment of intensive grinding effects on alumina as refractory compound: Acceleration of γ to α phase transformation mechanism
(Elsevier, 2014)
In this study, the feasibility of alumina phase transition enhancement by mechanical activation was conducted. It was showed that the milling environment plays an important role on the physical, chemical and thermal behavior ...
Synthesis and morpho-structural characterization of nanostructured magnesium hydroxide obtained by a hydrothermal method
(Elsevier, 2014)
Controlled magnesium hydroxide particles were successfully synthesized via a simple hydrothermal method. The influence of temperature and reaction time on the hydrothermal synthesis of Mg(OH)(2) was studied. The results ...

Synthesis, characterization and in vitro evaluation of divalent ion release from stable NiFe2O4, ZnFe2O4 and core-shell ZnFe2O4@NiFe2O4 nanoparticles
(Elsevier, 2020)
A simple organic-phase synthesis process was used to produce bare NiFe2O4 and ZnFe2O4 and core-shell ZnFe2O4@NiFe2O4 ferrite nanoparticles. X-ray powder diffractograms for all investigated powders show characteristic peaks ...
The influence of fluorine doping on the structural and electrical properties of the LiFePO4 powder
(Elsevier, 2017)
Low intrinsic electronic conductivity is the main disadvantage of LiFePO4 when used as a cathode material in lithium ion batteries. The paper offers experimental proofs of the theoretical prediction that fluorine doping ...
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 ...
Dielectric characteristics of donor-acceptor modified BaTiO3 ceramics
(Elsevier, 2016)
Sm/Mn codoped BaTiO3 ceramics were investigated for their microstructure and dielectric characteristics. The powders were prepared by the conventional solid state procedure. The concentration of Sm2O3 as a donor dopant has ...
Influence of different bonding and fluxing agents on the sintering behavior and dielectric properties of steatite ceramic materials
(Elsevier, 2017)
The focus of the study was on providing insights into interconnections between sintering and development of the crystalline microstructure, and consequently variations in dielectric behavior of four steatites fabricated ...
Nanostructured alumina particles synthesized by the Spray Pyrolysis method: microstructural and morphological analyses
(Elsevier, 2010)
Ultrafine particles or nanoparticles (ranging from a few nanometers to 100 nm) are of considerable interest for a wide variety of applications, ranking from catalyst to luminescence ceramics, due to their unique and improved ...
