Hydroxyapatite nanopowders prepared in the presence of zirconium ions
(Elsevier, 2014)
Hydroxyapatite nanopowders were prepared in the presence of different concentrations of zirconium ions. Such crystallization conditions yielded significantly reduced particle size and increased specific surface area. Cell ...
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 ...
Mechanically activated coal ash as refractory bauxite shotcrete microfiller: Thermal interactions mechanism investigation
(Elsevier, 2014)
A growing demand for refractory castables with advanced properties has given rise to a continuous technological evolution and highlighted the necessity for secondary raw materials reapplication even in refractory industry. ...
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 ...
The influence of mechanical activation on the electrical properties of Ba0.77Sr0.23TiO3 ceramics
(Ceramics International, 2014)
Ferroelectric barium strontium titanate (Ba0.77Sr0.23TiO3), BST, was prepared by solid-state reactions using as the starting compounds powder of barium carbonate (BaCO3), strontium carbonate (SrCO3) and titanium dioxide ...

Sintering of cordierite in the presence of MoO3 and crystallization analysis
(Belgrade : International Institute for the Science of Sintering, 2014)
Cordierite (MAS) is difficult to sinter because of the very narrow sintering temperature range (1300-1400ºC). Because a low temperature process is desirable, it is necessary to find functional ads which can allow easier ...
