Abstract

Provided is a method for easily manufacturing large volumes of a metallic glass nanowire with an extremely small diameter. This metallic glass nanowire manufacturing method is characterized in that a melted metallic glass or a master alloy thereof is gas-atomized in a supercooled state.

Claims (8)

1. A method for manufacturing metallic glass nanowire, characterized in that melted metallic glass or a master alloy thereof is subjected to gas atomization in a supercooled state.

2. The metallic glass nanowire manufacturing method according to claim 1 , characterized in that said metallic glass is one selected from the group consisting of a Zr-based, a Fe-based, a Pd-based, a Pt-based, and a Ni-based type.

3. The metallic glass nanowire manufacturing method according to claim 1 , characterized in that said gas atomization is carried out at gas pressure of 10 kgf/cm 2 or above.

4. The metallic glass nanowire manufacturing method according to claim 1 , characterized in that said metallic glass nanowires are in a fibrous state of an entanglement of a plurality of the metallic glass nanowires.

5. The metallic glass nanowire manufacturing method according to claim 4 , characterized in that said gas atomization is carried out at gas pressure of 70 kgf/cm 2 or above.

6. The metallic glass nanowire manufacturing method according to claim 2 , characterized in that said gas atomization is carried out at gas pressure of 10 kgf/cm 2 or above.

7. The metallic glass nanowire manufacturing method according to claim 2 , characterized in that said metallic glass nanowires are in a fibrous state of an entanglement of a plurality of the metallic glass nanowires.

8. The metallic glass nanowire manufacturing method according to claim 7 , characterized in that said gas atomization is carried out at gas pressure of 70 kgf/cm 2 or above.
