| 简介 |
A rare earth sintered magnet that realizes a high remanent flux density without detriment to coercive force and mechanical strength. There is provided a rare earth sintered magnet comprised of a sintered body whose carbon content determined by mass spectrometry is in the range of 500 to 1500 ppm, and wherein the cv-value of carbon content at a rupture plane thereof is ≤ 200. This rare earth sintered magnet can be produced through the step of performing, in a magnetic field, pressure molding of a raw material alloy powder whose carbon content determined by mass spectrometry is ≤ 1200 ppm and wherein providing that with respect to the characteristic X-rays of carbon determined by EPMA (Electron Probe Micro Analyzer), Cmax refers to the maximum value of X-ray intensity while Cmin refers to the minimum value of X-ray intensity, the ratio of Cmax/Cmin is ≤ 15 to thereby obtain a molding, and the step of sintering the molding. |
