This invention refers to a method for the surface treating of magnetic particle. An easily vaporized soluition of a certain chemical agent, for which titanate, phosphate or organo-silicon compound may be adopted, is passed into a reducing-oxidizing furnace or a closed vessel, and the applied agent will be adsorbed at the surface of the magnetic particle after the solvent is vaporized. The surface treated magnetic particle will show good lipophillcity, its dispersibility and filling performance in adhesive agent are improved as well. Magnetic tape made from the said magnetic particle offers a strong bound-magnetic film and a good smooth finish, and fine magnetic electroacoustic performance thereby. |
