MANUFACTURE OF RARE EARTH INTERMETALLIC COMPOUND MAGNETIC MATERIAL COMPOSED OF RARE EARTH COMPOUND

摘要

PURPOSE: To manufacture rare earth intermetallic compound magnetic material which contains nitrogen, carbon, boron, etc., at low cost by using corresponding rare earth nitride, carbide, boride, etc., as the material. ;CONSTITUTION: Rare earth nitride, carbide, boride, etc., composed of rare earth compounds such as rare earth oxide and halide lower in cost than metal are high frequency fused or arc fused with iron, cobalt, titanium, etc., and intermetallic compound which contains corresponding non-metal ingredients such as nitrogen, carbon, boron, etc., is manufactured. The concentration of nitrogen, carbon, boron, etc., contained in a sample is adjusted at need by heat treatment in various types of atmospheres such as hydrogen and adding a small quantity of rare earth metal, iron, cobalt, carbon, boron, etc., and fusing it again.;COPYRIGHT: (C)1994,JPO&Japio
