| Abstract: | in culer to prepare magnetic particles having high qualities in thai shape,she and magnetic property etc.satisfying the needs for a duplicating developer,theeffch of proal seledion and conditions in the fabrication of ulhafme FelOn particlesthrough the alkaline method are studied.These include the relationship among the rawmaterials, alkaboty raho, tempreature,rate of air-flow and the of oxidation etc.PropertieS of particles of Japanese and ChineSe origin are compared with those madewith the optimized under discussion.It is shown that properties of produCtSmade with this process has attained or sUrpassed the standard of domesic products andare on a par with the level of bootal magnetic particles from Japan. |
