Title:
混合酸化物および永久磁性粒子の製造方法
Document Type and Number:
Japanese Patent JP2014527282
Kind Code:
A
Abstract:
Method for the production of mixed oxides and permanent magnetic particles, based on rare earths-transition metals to produce RETM magnetic materials, comprising the preparation of a parent compounds mixture; introducing the parent compound mixture into a reactor with heat energy input, where the atomization die generates fine droplets as spray or aerosol; subjecting the fine droplets formed to pyrolysis and combustion, and; reducing the mixed oxide particles formed and collected as homogenous powder, obtaining permanent magnetic particles; being a simple method and allowing to obtain homogeneous and versatile compositions, especially for Rare Earth - Transition Metal (RETM) type permanent magnets, where RE (rare earth) can be, for example, an element such as neodymium, praseodymium, dysprosium or a combination thereof, among other possibilities, and TM (transition metal) can be, for example, iron, cobalt, nickel or a combination thereof.
