Method for producing nanopowders using electrical wire explosion

Abstract

A method for producing nanopowders using electrical wire explosion is provided, which includes forming a wire in a helical spring structure, supplying the formed wire to a supplier, electrically exploring the wire through applying high voltage to the wire after supplying the wire that is supplied to the supplier into a chamber, and collecting nanopowders generated through explosion of the wire, wherein the wire formed in a helical spring structure has a pitch of 0.4 to 0.8 mm, a number of coils of 10 to 13, and a diameter of 1 to 2 mm.

What is claimed is: 
     
         1 . A method for producing nanopowders using electrical wire explosion comprising:
 forming a wire in a helical spring structure;   supplying the formed wire to a supplier;   electrically exploring the wire through applying high voltage to the wire after supplying the wire that is supplied to the supplier into a chamber; and   collecting nanopowders generated through explosion of the wire,   wherein the wire formed in a helical spring structure has a pitch of 0.4 to 0.8 mm, a number of coils of 10 to 13, and a diameter of 1 to 2 mm.   
     
     
         2 . A method for producing nanopowders using electrical wire explosion comprising:
 supplying a wire to a supplier;   forming the wire that is supplied to the supplier in a helical spring structure, supplying the formed wire into a chamber, and electrically exploring the wire through applying of high voltage to the formed wire after supplying the wire that is supplied to the supplier into a chamber; and   collecting nanopowders generated through explosion of the wire,   wherein the wire formed in a helical spring structure has a pitch of 0.4 to 0.8 mm, a number of coils of 10 to 13, and a diameter of 1 to 2 mm.   
     
     
         3 . The method for producing nanopowders according to  claim 1 , wherein an end portion of the wire that is formed in a helical spring structure is formed in any one of close end, open end, tangent tail end, and pig tail end shapes. 
     
     
         4 . The method for producing nanopowders according to  claim 2 , wherein an end portion of the wire that is formed in a helical spring structure is formed in any one of close end, open end, tangent tail end, and pig tail end shapes.
