Abstract
The method for producing a mother alloy for an iron-based amorphous alloy has the steps of (a) melting raw materials for elements constituting the amorphous alloy together with at least one oxide of an element constituting the amorphous alloy, the raw materials containing aluminum as an inevitable impurity, and the oxide having a smaller standard free energy of formation than that of Al O in an absolute value; and (b) removing the resultant Al O from the melt, thereby reducing the content of aluminum to 50 ppm or less in the melt.
