Abstract
Disclosed are a method of manufacturing a uranium target, the method including (a) a step of preparing a conjugate including a matrix and a uranium target green compact formed in the matrix; and (b) a step of performing thermo-mechanical treatment through additional heat treatment at 530° C. to 600° C. during a hot rolling pass in a process of hot-rolling the conjugate, and a method of extracting radioactive Mo-99 using the uranium target.
Claims8
A method of manufacturing a uranium target, the method comprising:
- manufacturing a uranium green compact by mixing and compacting a uranium-aluminum alloy powder and an aluminum powder, where the content of aluminum in the uranium-aluminum alloy powder is 20% by weight or less;
- preparing a conjugate by combining an aluminum matrix and the uranium green compact;
- and
- performing a process of hot-rolling the conjugate comprising hot roll passes at a temperature of 530° C. to 600° C. for 7 to 20 hours.
