ABSTRACT:
This is a process for producing an iron-boron-silicon-carbon composition for a magnetic amorphous alloy. This process utilizes the silicon reduction of B.sub.2 O.sub.3 and avoids using expensive ferroboron as an ingredient. It also results in an alloy which is substantially free from aluminum impurity. The process uses a mixture of an iron containing constituent, a silicon containing constituent, a carbon-containing constituent and boric acid. Only 1-1.75 times the stoichiometric boron-containing amount of boric acid is required. The iron constituent is preferably selected from iron, iron oxide, ferrosilicon, carbon in iron and mixtures thereof. The silicon constituent is preferably selected from silicon, ferrosilicon, and mixtures thereof. The carbon constituent is preferably selected from the group consisting of carbon, carbon in iron and mixtures thereof. The reaction produces molten iron-3% boron-5% silicon alloy with up to 1% carbon. The reaction also produces a silicon dioxide containing slag.
