<p>Structural treatment of precipitated ferrites of magnetite or magnetoplumbite type from aqueous and aqueous alcoholic solutions and dispersions, performing while boiling and with the possible interaction of separation forces, arising through the action of ultrasound, electrohydraulic impulses, liquid flow and similar phenomena, connected with changes in the mutual position of particles. During the precipitation of ferrites a changing magnetic acts in the precipitating environment with an intensity from 0.001 to 5 T at a speed of movement of the magnetic field point from 1 to 2,000 m/s. The frequency of change of the magnetic field ranges from 0.1 to 1,200 s<-1> modified in solution by the action of mechanical separator forces, occurring during the flow of solution in a range of flow rates from 0.001 to 20 m/s according to indirect proportion.</p> |
