Development of Microwave Ferrites for High Performance Applications,

Abstract

LiZn ferrites were investigated to control the resultant microstructure or to obtain nanoscale powders at a low temperature. Two nonconventional chemical methods are introduced. The sol-gel coating procedure was used to uniformly distribute additives like SiO2 and Bi2O3. These oxides improved the densification of the LiZn ferrites at low temperatures via a liquid phase sintering. Nanocrystalline LiZn ferrites were obtained at a low temperature of 400 deg C via the assistance of a combustible acid like polyacrylic acid.
