在900℃下,采用循环伏安法对CaCl2-CaO熔盐中金属钙的电沉积行为进行了研究。研究结果表明,在CaCl2熔盐中加入CaO后,熔盐中Ca2+的还原电位正移,且Ca2+的还原过程受扩散控制。
Electrodeposition of metallic calcium in CaCl2-CaO molten salt was investigated by cyclic voltammetry at 900 ℃. The results show that the addition of CaO to CaCl2 molten salt, the reduction potential of Ca2 + in molten salt is positive, and the reduction of Ca2 + is controlled by diffusion.
