Abstract

PURPOSE:To reduce variation in characteristic of dust magnet intended to manufacture later by depressing evaporation of rare earth elements with lowered melting temp. in such a way that even rare earth elements are put into the melting pot from the beginning for manufacturing rare-earth cabalt alloy ingot.
