Abstract: PURPOSE: To easily disperse and simultaneously easily orient ferromagnetic powder by packing the ferromagnetic powder into the pore spaces of porous and non-magnetic mineral skeleton materials having the pore spaces dug in parallel or almost in parallel. CONSTITUTION: An inorganic skeleton materials are formed of crystal isopoly or heteoisopoly oxide, carbide, nitride, or oxide having plural pore spaces. The pore spaces of the mineral skeleton materials are arranged in parallel or almost in parallel, preferentially, like a symmetrical hexagonal honeycomb structure. Then, ferromagnetic partitles such as chrome dioxide and ferrite are packed into the pore spaces of the mineral skeleton materials. Thus, the ferromagnetic particles can be easily dispersed and easily oriented.
