초록
우라늄금속의 전해정련에서 발생한 석출물의 형태와 전류밀도와의 관계를 분석하였다. 석출물은 300 mA/cm2의 전류밀도 범위에서 사방형특징을 가진 우라늄 결정이 연결되어 생성되는 반면에, 100 mA/cm2 이하의 낮은 전류 밀도에서는 whisker형태의 석출물이 생성되었다.
The morphology of the deposit produced by electrorefining of uranium metal was analyzed to find out a correlation with the current density. The uranium deposits were comprised of chain-like uranium crystal with a rhomboidal shape at over 300 mA/cm2 current density, while the whisker-like dendrites were observed at lower current density than 100 mA/cm2.
