Abstract
Abstract In this paper we describe a new method for preparing fine high-frequency ferrite powders. According to our method, the substances in the reaction are metal nitrates and ammonium hydroxide, the coprecipitation takes place into a colloidal medium and the reaction of forming ferrite is a quick combustion. By eliminating decanting, ablution, filtering, this method insures a precise composition of the final product. The necessary materials are easy to obtain and the preparation technique is relatively simple and with low energy costs.
