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 ...
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 ...
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 ...
Sintering process influence on microstructure and intergranular impedance of rare-earth modified BaTiO3-ceramics
(Belgrade : International Institute for the Science of Sintering, 2011)
Sintering process is a complex of different synergetic effects during the ceramics materials consolidation. The microstructural level properties control is very important as a stage in advanced materials prognosis. SEM ...
Ho2O3 Additive Effects on BaTiO3 Ceramics Microstructure and Dielectric Properties
(Belgrade : International Institute for the Science of Sintering, 2012)
Doped BaTiO 3-ceramics is very interesting for their application as PTCR resistors, multilayer ceramic capacitors, thermal sensors etc. Ho doped BaTiO 3 ceramics, with different Ho 2O 3 content, ranging from 0.01 to 1.0 ...
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 ...
