AB  - In this work single phase hexagonal YMnO3 powders were prepared starting from Y(CH3COO)(3)center dot xH(2)O, Mn(CH3COO)(2)center dot 4H(2)O, KMnO4 and KOH using methods of conventional (280 degrees C for 6 h) or microwave assisted hydrothermal synthesis (200 degrees C for 2 h) followed by calcination at 1200 degrees C for 2 h. According to FESEM analysis the calcined powders consisted of submicronic YMnO3 particles, which were uniform in shape and size. Ceramic samples were obtained by sintering the as-synthesized powders at 1400 degrees C for 2 h. XRD analysis confirmed the presence of the single phase hexagonal YMnO3. SEM analysis showed a dense and homogeneous microstructure with typical inter- and intra-grain cracks. Magnetic measurements indicated ferrimagnetic properties that were explained by non-stoichiometry of the obtained compound and an excess of manganese that was confirmed by ICP analysis.

AB  - The possibility of mechanochemical synthesis of the lead magnesium niobate (PMN) powders of the composition Pb(Mg1/3Nb2/3)O-3 in iron vials was investigated. According to X-ray and energy-dispersive spectroscopy (EDS) analysis of the obtained powder mixtures, milling in iron vials resulted in incorporation of Fe and formation of PFN of composition Pb(Fe1/2Nb1/2)O-3 simultaneously with formation of PMN. Relative amounts of PMN and PFN were determined based on values of Curie temperature and lattice constant of perovskite phase. Although only 1 wt pct of Fe was incorporated, a stoichiometry of the system was significantly changed, resulting in formation of pyrochlore phase and excess MgO. Single-phase perovskite was obtained when the excess of PbO and Nb2O5 was added during mechanochemical synthesis. Because the dielectric properties were worse than expected, the alternative ways for improvement of dielectric properties were tried and discussed.
