The present invention is to provide powder made of iron-based metallic glass, the corrosion resistance of which is improved over the conventional powder made of iron-based metallic glass. The basic composition includes a group of iron-based metallic elements that predominantly has Fe, a group of metalloid elements that consists of Si, B, P, and C, and a little amount of a group of elements for improving the degree of supercooling that consists of either or both of Nb and Mo. The powder made of the iron-based metallic glass is obtained by adding to the basic composition an element for improving the corrosion resistance. The obtained powder made of the iron-based metallic glass has an excellent corrosion resistance, an excellent magnetic property, and an excellent insulating property.

Various embodiments provide apparatus and methods for melting materials and for containing the molten materials within melt zone during melting. Exemplary apparatus may include a vessel configured to receive a material for melting therein; a load induction coil positioned adjacent to the vessel to melt the material therein; and a containment induction coil positioned in line with the load induction coil. The material in the vessel can be heated by operating the load induction coil at a first RF frequency to form a molten material. The containment induction coil can be operated at a second RF frequency to contain the molten material within the load induction coil. Once the desired temperature is achieved and maintained for the molten material, operation of the containment induction coil can be stopped and the molten material can be ejected from the vessel into a mold through an ejection path.
