전해제련법을 이용하여 <TEX>$LiF-BeF_2-ZrF_4$</TEX> (67-27-6 mol%) 용융염에서 Zr 금속 분리실험을 수행하였다. <TEX>$LiF-BeF_2$</TEX> (72-28 mol%) 용융염과 <TEX>$LiF-BeF_2-ZrF_4$</TEX> (67-27-6 mol%) 용융염의 분해 전압은 각각 -1.55, -1.35 volt로 측정되었고, Zr 분리실험 결과 인가전압 범위는 -1.4 -1.5 volt 사이가 적당하였다. 인가전류가 증가할수록 전착량은 증가하나 전류효율은 감소하였다. 그리고 반응온도가 증가할수록 <TEX>$ZrF_4$</TEX>의 기화로 인하여 전착량과 전류효율이 감소하였다.
A study on the separation of Zr metal from <TEX>$LiF-BeF_2-ZrF_4$</TEX> (67-27-6 mol%) molten salt was carried out using electrowinning. The decomposition potentials of the <TEX>$LiF-BeF_2$</TEX> (72-28 mol%) and the <TEX>$LiF-BeF_2-ZrF_4$</TEX> (67-27-6 mol%) molten salts were measured to be -1.55 and -1.35 volt, respectively. The Zr separation voltage from the salt were found to be in a range of -1.4 -1.5 volt. As increasing applied current, the deposition of molten salt on a cathode increases but the current efficiency decreases. In addition, the deposition and current efficiency decreases with increasing temperature.
