摘 要:提要在975K和氧化铝浓度为(2—8)×10-5mol·cm-3的条件下,应用计时库仑法、计时电流法和电位扫描法测定了铝从AlCl3-NaCl-KCl熔体中电解析出的反应速度.测定结果表明铝的析出为快速反应.
Abstract: By use of chronocoulometry, potential sweep voltammetry and chrono amperometryat short time the rate constant was determined at 975K in electrolyte of equimolarNaCl-KCl melts with aluminium chloride concentration of (2-8)×10-5mol·cm-3.The studv showed that the aluminium deposition reaction was a fast reaction.
