In this papor,a survey of the preduction,market,applieation and technological advance ofmajor magnetic materials such as porrnanent magnet,soft magnet,magnetic recording mediurn,et al, hasbeen summarily discussed and suggestions recommended.

In the production of soft ferrite material and cores, the activity (specific surface area) of raw materials has considerable influence on the process and properties, and sintering is one of the key procedures affecting the material properties.

According to the working principle and structure speciality of magnetic circuit of microwave ferrite shifter, the technical requirements for soft ferrites as yokes of microwave ferrite shifters were analyzed, including the main parameters and dimensions, temperature stability, permeability and its frequency spectrum, active energy, stress sensitivity, etc.

Broad temperature low loss FPT type soft ferrite material and core are mass-produced in common roller-kiln.

A new process of high-purity iron oxide red for soft magnetic ferrite use;

The progress on the study of preparing soft magnetic ferrite ultrafine powder;

A commercial test was made for preparation of 500 t/y high performance Mn-Zn soft magnetic ferrite powders by direct co-precipitation.
