Hydrothermally assisted synthesis of YMnO3

In this work single phase hexagonal YMnO3 powders were prepared starting from Y(CH3COO)3·xH2O, Mn(CH3COO)2·4H2O, KMnO4 and KOH using methods of conventional (280°C for 6h) or microwave assisted hydrothermal synthesis (200°C for 2h) followed by calcination at 1200°C for 2h. According to FESEM analysi...

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°C for 2h. 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.Institute for Multidisciplinary Research, University of Belgrade, Kneza Višeslava 1a, 1030 Belgrade, SerbiaInstituto de Química, Universidade Estadual Paulista-UNESP, R.
