Microstructure changes caused by thermal etching of sintered ZnTiO3
(2014)
Polishing and thermal etching was performed on ZnTiO3sintered ceramic. Two set of specimens were recorded, on higher 1200oC/1100oC sintered/etched, and lower 900oC/800oC sintered/etched. Phase composition, crystallite sizes ...
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 ...
Peculiarities in sintering behavior of Ca-deficient hydroxyapatite nanopowders
(Elsevier, 2012)
We report unusual sintering behavior of Ca-deficient hydroxyapatite processed with different heating rates; particularly, faster heating resulted in higher densification. We hypothesize that faster heating delays formation ...
Dense fine-grained biphasic calcium phosphate (BCP) bioceramics designed by two-step sintering
(Elsevier, 2011)
In this study, dense, fine-grained biphasic calcium phosphate bioceramics were designed via the two-step sintering method. The starting powder was nanosized calcium-deficient hydroxyapatite, whose phase composition, average ...
Microstructure and dielectric properties of Dy/Mn doped BaTiO3 ceramics
(Elsevier, 2014)
Dy/Mn doped BaTiO3 with different Dy2O3 contents, ranging from 0.1 to 5.0 at% Dy, were investigated regarding their microstructural and dielectric characteristics. The content of 0.05 at% Mn was constant in all the ...
