  Self-propagating high-temperature synthesis of MnZn-ferrites for inductor applications

  摘要：

  The self-propagating high-temperature synthesis (SHS) route is evaluated for the synthesis of MnZn-ferrite powders that are subsequently processed towards the manufacturing of high initial magnetic permeability polycrystalline specimens for inductor applications. The conditions for the synthesis of particular phases by SHS reactions between iron metal and oxide powders were optimized and the effects of the synthesis parameters on ignition and propagation characteristics were studied. By "fine-tuning" the synthesis parameters, products of a wide spectrum of phases from single-phase, pure and well crystallized (MnxZny)Fe2+deltaO4 to the oxide of the divalent metals (MnxZnyFe1-x-y)O could be controllably synthesized. Advantages of the synthesis route are demonstrated by tests on properties of merit on final products: combustion powder products were subsequently pressed to torroids, sintered and characterized with respect to their magnetic properties, in comparison to conventionally synthesized samples of the same composition. When sintered under appropriate schedules of oxygen partial pressure profile to avoid phase oxidation at 600degreesC, SHS powders could be processed to high permeability MnZn-ferrites. At equal average particle sizes SHS powders exhibit higher reactivity and grain growth compared to conventionally synthesized powders. This advantage can be utilized in the manufacturing of high permeability MnZn-ferrites with shorter firing schedules and thus all associated advantages in terms of productivity, production costs or zinc evaporation loss.

  Tunable dielectric constant with transition metals doping in Zn1−x(MnTM)xO (TM=Co, Fe) nanocrystals

  摘要：

  We have presented dielectric studies on Zn1-xMnx/2Fex/2O and Zn1-xMnx/2Cox/2O (x = doping level) semi-conducting nanoparticles (similar to 2-40 nm). Structural analyses show the formation of single phase nanoparticles. Dielectric constant (epsilon) is found to exhibit sensitive modulation, both with the variation of doping element (Fe and Co) and doping level (x) in ZnMnO matrix and also with frequency (f). Enhancement of epsilon is found to be similar to 1500 times for Zn0.9Mn0.05Fe0.05O and similar to 2 times for Zn0.9Mn0.05Co0.05O from that of Zn0.9Mn0.1O nanoparticles at low frequency region. The enhancement in e can be explained on the basis of dielectric polarization, caused by the presence of different abundance of higher oxidation states of Fe and Co ions in ZnMnFeO and ZnMnCoO samples. From our observation one can choose the suitable doping element, along with suitable dopant concentration to achieve the desired higher value of e in transition metal doped ZnMnO nanoparticles at room temperature. We have also estimated semiconducting band gap of those nanoparticles using recorded absorbance spectra. (C) 2015 Elsevier B.V. All rights reserved.
