METAL­CERAMIC CORE­SHELL STRUCTURED MAGNETIC MATERIALS POWDER PREPARED BY GAS PHASE PROCESS AND THE PREPARATION METHOD THEREOF

摘要

The present invention is a metal by the vapor phase process - provides a magnetic powder of the shell structure of the metal produced by a novel manufacturing method and the manufacturing method of manufacturing the magnetic powder of the shell structure-ceramic core ceramic core. In the present invention, conventional metal-having even though not only can replace the complex liquid phase process for synthesizing the magnetic powder of the shell structure by a vapor phase process, apply a flame spray pyrolysis process, which can not keep the prior art in a reducing atmosphere, and various composition-ceramic core metal-ceramic core - can be synthesized a novel material of the shell structure. Thus usefully applied to various applications such as heat storage materials, solar materials, auto parts, electronic materials. ;
