Abstract

The invention discloses a magnetic composite material and a preparation method thereof. The preparation method comprises the steps of preparation of a material A and preparation of a material B, preparation of a material C and preparation of a material D; and mixing the material A, the material B, the material C and the material D, and compacting to form a blank N; and carrying out sintering treatment and secondary tempering treatment on the blank N to obtain a rare-earth modified material. The problems that the traditional preparation method is complex and the comprehensive performance of theprepared magnetic composite material is not high are solved.

Description

technical field [0001] The invention relates to the field of inorganic materials, in particular to a magnetic composite material and a preparation method thereof. Background technique [0002] Rare earth permanent magnet material is the permanent magnet material with the highest comprehensive performance known now. It is more than 100 times higher than the magnetic properties of the magnet steel used in the nineteenth century, and it is much superior to ferrite and alnico. The magnetic properties of expensive platinum-cobalt alloys are twice as high. Since the use of rare earth permanent magnet materials not only promotes the miniaturization of permanent magnet devices and improves the performance of products, but also promotes the production of some special devices, so the appearance of rare earth permanent magnet materials immediately attracted great attention from all countries. Development is extremely rapid. The Chinese patent with the patent number CN201510546132.9 d...
