Abstract

The invention discloses a permanent magnet ferrite tile. The permanent magnet ferrite tile comprises, by weight, 10 to 20 parts of iron oxide, 2 to 10 parts of cerium oxide, 4 to 6 parts of soda, 2 to6 parts of boric acid, 1 to 3 parts of lanthanum oxide, 6 to 10 parts of chromium oxide, 2 to 8 parts of aluminum silicate fiber,1 to 6 parts of zinc oxide, and 2 to 6 parts of talc powder. Accordingto the invention, the comprehensive performance of the magnetic tile can be improved.

Description

technical field [0001] The invention relates to the field of magnetic tiles, in particular to a permanent ferrite magnetic tile. Background technique [0002] Permanent ferrite anisotropic sintered magnetic tiles are among many permanent magnet materials. With the best cost performance, they have become the most widely used and produced permanent magnet materials in the world. They are widely used in large exciters, auxiliary exciters, Motors in aircraft; small ones such as floppy drive and hard drive motors used in computers, motors in information products, electric bicycle motors, automobile motors, and many motors are required to be able to withstand high and low temperature, vibration, shock and DC electromagnetic field interference. Work. Since the permanent magnet ferrite magnetic tile is a key component in a DC motor, higher requirements are placed on the magnetic performance of the magnetic tile. However, the prior art magnetic tiles often suffer from poor performa...
