PURPOSE:To obtain widely useable polymer composite type magnet powder by replacing particles less than 30mum in R2T14B sintered product ground powder (R: rare earth element including Y, T: transition metal) with Sm2Co17 magnet powder. CONSTITUTION:R2T14B (R: rare earth element including Y, T: transition metal) polymer composite type magnet powder contains Nd, Fe and B as chief components. Thereupon, particles less than 30mum in diameter in the R2T14B sintered product ground powder is replaced with at least one kind of Sm2Co17 magnet powder and SmCo5 magnet powder. Hereby, a RTB polymer composite type magnet having high magnet characteristics is yielded. Thus, widely useable polymer composite type magnet powder is obtained. |
