METHOD FOR PRODUCING NONRETENTIVE MATERIAL Russian patent published in 1995 - IPC

Abstract RU 2040810 C1

FIELD: magnetic circuit manufacture. SUBSTANCE: method involves mixing of iron powder (90- 94 mass percent) and ferrophosphorus powder (6-10 mass percent) with phosphor content of 10-13 mass percent, their compaction and sintering in nitrogen atmosphere. EFFECT: reduced energy requirement due to lower cost of sintering atmosphere, improved safety in sintering, improved magnetic characteristics of nonretentive material obtained. 2 tbl, 1 dwg
