Preparation of nanostructured Zn-Cr-O spinel powders by ultrasonic spray pyrolysis
(Elsevier Sci Ltd, Oxford, 2001)
Ultrasonic spray pyrolysis (1.7 MHz) has been applied for the generation of zinc chromium oxide submicronic (470 nm) particles from the corresponding metal nitrate solution. Heterogeneous gas-liquid/solid chemical reactions ...
Correlation between densification rate and microstructure evolution of mechanically activated BaTiO3
(Abingdon : Taylor & Francis Ltd., 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 ...
Microstructural characteristics of calcium hydroxyapatite/poly-L-lactide based composites
(Wiley, 1999)
Besides its high osteoinductive properties, hydroxyapatite (HAp) exhibits a relatively low mechanical strength. In order to improve the mechanical properties and reliability of HAp based composites, the addition of selected ...
Microstructure and dielectric properties of BaTiO3 doped with Er2O3, Yb2O3 and Ho 2O3
(Faenza : ISTEC-CNR, 2008)
Doped barium-titanate ceramic is attracting much interest for its application as resistors with a positive temperature coefficient of resistivity (PTCR), multilayer ceramic capacitors (MLCC), thermal sensors etc. In this ...
Densification, Microstructure, and Electrical Properties of BaTiO3 (BT) Ceramics Prepared from Ultrasonically De-Agglomerated BT Powders
(Taylor & Francis, 2009)
In this study, a correlation between densification, microstructure, and electrical properties of BaTiO3 (BT) ceramics prepared from ultrasonically de-agglomerated BT powders has been analyzed. BT powders with the same ...
Evolution of the microstructure of disperse ZnO powders obtained by the freeze-drying method
(Lausanne : Elsevier Science, 2004)
Freeze-drying, as a cryochemical powder processing method is applied in the synthesis of ZnO submicrometer to narrosized powders. The process involves rapid freezing of the sprayed precursor solution, drying under vacuum ...
Niobium doping effect on BaTiO3 structure and dielectric properties
(Elsevier, 2020)
The effect of Nb on the microstructure and dielectric properties of BaTiO3 ceramics was investigated. The Nb/Mn–BaTiO3 ceramics were prepared using a conventional solid-state method. The concentration of Nb varied from 0.1 ...
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 ...
Investigating on the microstructure and optical properties of Au, Ag and Cu implanted TiN thin films: The effects of surface oxidation and ion-induced defects
(Elsevier, 2024)
In the present paper, the effects of metal ion implantation on the structural and optical properties of TiN thin films have been investigated. TiN films of 170 nm thickness were grown by d.c. reactive sputtering on Si (100) ...
