Mechanochemical synthesis Ba0.8Sr0.2TiO3
(Belgrade : Institute of Technical Sciences of SASA, 2011)
Ba0.8Sr0.2TiO3 was prepared from the starting materials BaCO3, SrCO3 and TiO2 through solid state reaction. Mixture of these oxides was mechanically activated using a high-energy ball mill at different time intervals from ...
Influence of mechanochemical activation on sintering of cordierite ceramics with the presence of Bi2O3 as a functional additive
(Belgrade : Materials Research Society of Serbia, 2011)
According to its exceptional electrical characteristics, such as low temperature expansion coefficient, low dielectric constant and good mechanical properties, cordierite, 2MgO⋅2Al2O3⋅5SiO2, represents very attractive ...
Paramagnetic nanoparticles in the regeneration of the reduced alveolar bone density
(Belgrade : Materials Research Society of Serbia, 2011)
One of the trends in the treatment of reduced bone density is in oral implantology through the use of new biomaterials with paramagnetic properties. In this in vivo study the effect of Ca /Co-HAp nanoparticles (calcium/c ...
Sintering of mechanically activated MgO-TiO2 system
(Belgrade : Institute of Technical Sciences of SASA, 2011)
Mixtures of MgO-TiO2 powders were mechanically activated in planetary ball mill for time interval from 0 to 120 minutes. The influence of mechanical activation on phase composition and crystal structure was analyzed by ...
Intergranular properties and structural fractal analysis of BaTiO 3-ceramics doped by rare earth additives
(Hoboken, NJ : John Wiley & Sons, 2011)
Ferroelectric BaTiO3 as one of the most important ceramics materials in electronic, used on wide range of applications, can be modified with various dopant ions. In this paper, the influence of Er2O 3, Yb2O3, Ho2O3 and ...
Structural and magnetic properties of nanocrystalline bismuth manganite obtained by mechanochemical synthesis
(Springer Netherlands, 2011)
We have studied the formation of BiMnO3 (BMO) nanocrystalline perovskite powder produced by high-energy milling of the constituent oxides. The crystal structure and the amount of crystalline and amorphous phases in the ...
Poly(D,L-lactide-co-glycolide)/hydroxyapatite core-shell nanospheres. Part 1: A multifunctional system for controlled drug delivery
