Abstract
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.
