3)  solvent extraction debinding
化学溶剂脱脂
4)  electrochemical deoxidation
电化学脱氧
1.
Molten CaCl2 was used to decrease the activity of the by-product CaO during the purification of rare earth yttrium by electrochemical deoxidation, in which the oxygen was removed as CO or CO2 gases from the graphite anode.
在电化学脱氧提纯金属钇的过程中,利用熔融的CaCl2使其副产品CaO的活度降低,脱去的氧以CO或CO2气体的形式从石墨阳极放出,只要电解条件合适,可使脱氧极限无限降低,同时金属钙是由CaCl2电解所得,较Ca-CaCl2熔盐脱氧提纯金属钇的方法,它降低了由于金属Ca的不纯而引入的杂质污染。

补充资料:电化学脱脂
分子式:
CAS号:

性质:将待脱脂的电镀零件置于碱性溶液中作为阴极或阳极,通过电解清除其表面油脂的过程。电化学脱脂的方式有阴极脱脂、阳极脱脂和阴阳极联合脱脂。阴极脱脂适用于有色金属件,如铝、锌、锡、铅、铜及其合金件;阳极脱脂适用于硬质高碳钢、弹性材料零件;阴阳极联合脱脂用于无特殊要求的钢铁件。电化学脱脂比化学脱脂的效果好。因为在电极上析出的气体能大大加速脱脂过程中的皂化作用和乳化作用。
