Structural characterization of Li-MN doped powders prepared by Pechini's method
(Trans Tech Publications Ltd, 2001-01-01)
Pechini's method has been successfully used to prepare Li-doped MgNb2O6(MN) at short time and low temperature. It consists in the preparation of metal citrate solution, which is polymerized at 250°C to form a high viscous ...
The influence of the sintering system on PMN properties
(2003-03-15)
PMN powder samples with PbO excess of 0, 1,2 and 3% were submitted to the pressing and sintering at 1200°C for 4h with a heating rate of 3°C/min. A new sintering system, developed at our laboratories, was used. It allows ...

Effect of magnesium on structure and properties of LiNbO3 prepared from polymeric precursors
(Elsevier B.V., 2002-01-01)
The effect of magnesium addition on the phase formation and electric properties of LiNbO3 powder prepared from polymeric precursor was analyzed. It was shown that the unit-cell volume of the rhombohedral phase decreased ...
Mechanochemical synthesis of lead magnesium niobate ceramics in iron media
(Springer, 2008-04-01)
The possibility of mechanochemical synthesis of the lead magnesium niobate (PMN) powders of the composition Pb(Mg(1/3)Nb(2/3))O(3) in iron vials was investigated. According to X-ray and energy-dispersive spectroscopy (EDS) ...

Phase analysis of seeded and doped PbMg1/3Nb2/3O3 prepared by organic solution of citrates
(1996-07-01)
PbMg1/3Nb2/3O3 (PMN) prepared by organic solution of citrates was analyzed by the Rietveld method to determine the influence of seeds and dopants on the perovskite and pyrochlore phase formation. It was observed that ...
