Abstract
The effect of Pb substitution on the properties of Ba3(1-x)Pb3xCo2Fe24O41 h exaferrite sintered at low temperatures was investigated. The formation of Z-type phase and the densification of the sintered ferrites depended on sin tering temperature and Pb content. The modified ferrite sintered at 1120 de grees C/4 h with x = 0.20 stoichiometry, consisted mainly of Z-type hexagon al phase and exhibited good hyper-frequency properties as follows: 5.0 init ial permeability, about 1.5 GHz cut-off frequency, > 5 quality factor. Inte resting dielectric resonance was found in the hyper-frequency region. (C) 1 999 Published by Elsevier Science S.A. All rights reserved.
