Title:
SN-TI ALLOY POWDER FOR SUPERCONDUCTING WIRE ROD, METHOD FOR PREPARING SAME, AND METHOD FOR MANUFACTURING SUPERCONDUCTING WIRE ROD USING SAME
Document Type and Number:
WIPO Patent Application WO/2021/066376
Kind Code:
A1
Abstract:
The present invention pertains to: a Sn-Ti alloy powder for a superconducting wire rod, the Sn-Ti alloy powder making it possible to improve superconducting properties by minimizing the size of Sn-Ti particles dispersed in a Sn-based alloy; a method for preparing same; and a method for manufacturing a superconducting wire rod using same, and is characterized in that a Sn-Ti alloy is melted to produce a Sn-Ti intermetallic compound having an average particle size of 3 µm or less, and the content of Ti in the entire alloy is 0.5-3 wt%. The method for preparing the Sn-Ti alloy powder for a superconducting wire rod is characterized by comprising: a Sn-Ti alloy melting step for melting a Sn-Ti alloy or Sn-Ti alloy processed material; and a Sn-Ti alloy powder formation step for spraying and solidifying a molten Sn-Ti alloy through a nozzle in an inert gas atmosphere.
