本工艺采用熔融氟化锂-氟化镨钕-氟化钆熔盐三元体系为电解质,通过电解氧化钆与氧化镨钕混合物的方法,制备了成分稳定的镨钕钆合金,同时就电解质组元、温度、阴极电流密度、加料速度对电解过程的影响进行了试验研究。结果表明:在试验条件下可以生产钆含量(10~15)%±0.5%(质量分数)的镨钕钆合金,金属直收率大于98%,电流效率大于78%;产品含碳小于0.05%,含铁小于0.3%,含Ca,W均小于0.01%,同时具有成本低、工艺稳定、产品质量好等优点。
The process uses a molten lithium fluoride - praseodymium neodymium - gadolinium fluoride molten salt ternary system as an electrolyte, gadolinium oxide and praseodymium oxide by electrolysis mixture prepared a stable composition praseodymium neodymium gadolinium alloy, at the same time on the electrolyte group The effects of element, temperature, cathodic current density and feed rate on the electrolysis process were studied. The results show that the praseodymium neodymium gadolinium gadolinium with the content of gadolinium (10-15% ± 0.5%) can be produced under the experimental conditions with the direct metal yield of more than 98% and the current efficiency of more than 78%. The carbon content of the product is less than 0.05% , Iron less than 0.3%, containing Ca, W are less than 0.01%, at the same time with low cost, process stability, good product quality and so on.
