Изобретение относитс  к цветной Пример Графитовый катод про- металлургии и может быть использова- питьгоают в солевом расплаве, затемThe invention relates to a color example. A graphite cathode of pro-metallurgy can be used in a molten salt, then

помещают в муфельную печь и вьщержи- вают истечение 6 ч при после 5 чего- образцы взвешиваютplaced in a muffle furnace and depressed for 6 hours; after 5 minutes, the samples are weighed

Результаты обработки в различных солевых расплавах приведены в таблице .The results of processing in various salt melts are given in the table.

но в процессе восстановлени  катодов электролизера дл  рафинировани  алюмини .but in the process of recovering the cathodes of an electrolyzer for refining aluminum.

Цель изобретени  - повышение срока службы катодов и улучшение условий трудасThe purpose of the invention is to increase the service life of the cathodes and to improve the working conditions
