Summary

Magnetic fine powder whose electromagnetic parameters can be easily controlled was prepared by the polycarbonsilane precursor mixed with magnetic fine powder and subsequently heated at different temperatures. The phase composition and the electromagnetic characteristic of fine powder were analyzed. The processing parameters were optimized. The effect of the kind and the amount of the mixed magnetic fine powder, as well as the temperatures on the electromagnetic properties of the composite fine powder was studied. Under the processing routine presented in this paper, composite fine powder possessing different electromagnetic properties can be prepared.
