Chinese Patent: CN 1118012A Patentee:Mr. Shencheng Tao, Beijing Subject:Process for High Curie Temperature Amorphous RE Magnetic Material Abstract: The invention covers a heat treatment process for high Curie temperature amorphous rare earth magnetic material powder. The .conventional heat treatment process for high Curie temperature rare earth magnetic material powder with a size range 0.3—10 micron usually results in law efficiency, high cost and the oxidation of the powder when the temperature is raised from room temperature to the phase transition point. The invented process has solved these problems by controlling the following 4 steps: a. searching for phase transition point, b. searching for Curie point, c.
