| 摘要 |
A composition which exhibits high induced magnetism in a small applied magnetic field when formed into a magnetically stabilized fluidized bed and which comprises particles containing a nonferromagnetic component, or components, composited with one or a plurality of elongated ferromagnetic components oriented and present in each of said particles in relatively low concentration, based on the total volume of the particles; and a process wherein such composite particles are formed into a magnetically stabilized fluidized bed and contacted with a fluid, preferably gas.
