ABSTRACT Phosphorus rich transition metal alloys are pro- tected by a layer of boron oxide during the melting pro- cess. The presence of the boron oxide layer prevents the evaporation of phosphorus values. Melting of phosphorus- containing iron/nickel/cobalt based glass-forming alloys under a refining metal oxide/boron trioxide flux reduces undesirable metal oxide impurities, such as titanium dio- xide impurities, prevents oxidation of the melt, and re- duces loss of phosphorus values from the melt.
