Sintering Effects on Microstructure and Electrical Properties of CaCu3Ti4O12 Ceramics
(Hoboken, NJ : John Wiley & Sons, 2013)
CCTO powders were prepared by solid state reaction and mechanochemically, respectively. Synthesized powders were characterized by XRD, FE-SEM and PSA techniques. The sinterability of CCTO powders was investigated by heating ...
Microstructure Samples Preparation and Analysis on the Way for Statistical and Fractals Applications
(Belgrade : Serbian Ceramic Society, 2014)
The new correlation between microstructure and dielectric properties of doped BaTiO3-ceramics based on fractal geometry and contact surface probability has been developed. The doped BaTiO3-ceramics using in this investigation ...
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 ...
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 ...
Microstructure and EDS Contact Surfaces Characterization for Statistical Analysis of Doped BaTiO3-Ceramics
(Belgrade : Serbian Ceramic Society, 2012)
Barium-titanate based ceramics belongs to one of very important group of functional ceramics that can be used on a large scale of applications. The properties of BaTiO3 based ceramics are fundamentally correlated with grain ...
Fractal corrections of BaTiO3-ceramic sintering parameters
(Belgrade : International Institute for the Science of Sintering, 2014)
Morphology of ceramics grains and pores as well as Brownian character of particle dynamics inside ceramics specimen contributes to better understanding of the sintering process. BaTiO3-ceramics, studied in this paper, has ...
Intergranular fractal impedance analysis of microstructure and electrical properties of rare-earth doped BaTiO3
(Hoboken, NJ : John Wiley & Sons, 2010)
Microstructure properties of barium-titanate based materials, expressed in grain boundary contacts, are of basic importance for electric properties of these material. In this study, the model of intergranular impedance ...
Tailoring and Processing of Defect Free Barium Titanate Stannate Functionally Graded Ceramics: BTS2.5/BTS5/BTS7/BTS10 FGMs
(Paris : Atlantis Press, 2017)
Four-component barium titanate stannate (BaTi1−x Sn x O3, BTS) functionally graded materials (FGMs) were designed, processed and examined. BTS powders with different tin content (x = 0.025, 0.05, 0.07 and 0.10, abbreviated ...
Facile synthesis of poly(ε-caprolactone) micro and nanospheres using different types of polyelectrolytes as stabilizers under ambient and elevated temperature
(Elsevier, 2013)
Poly(ε-caprolactone) (PCL) particles were prepared by physicochemical method with solvent/non-solvent systems. The synthetic polymer polyvinylpyrrolidone (PVP) and natural polymer poly(α,γ,l-glutamic acid) (PGA), were used ...
Preparation and properties of porous, biomorphic, ceria ceramics for immobilization of Sr isotopes
(Elsevier, 2013)
A new technology for radionuclide trapping which is based on bio-templating approach was proposed in this paper. Porous oxide ceramics was prepared by wet impregnation of biological template with water solution of cerium ...
