METHOD OF PALLADIUM POWDER PRODUCTION |
摘要 |
chemical- metallurgical production of platinum metals, particularly, production of powder of palladium reduced from middlings of platinum metals production in form of palladium sponge. SUBSTANCE: method consists in that heating of oxidized ground palladium sponge in process of reduction and cooling of reduced product are carried out in current of ammonia-nitrogen gas mixture at heating temperature of 200-500 C and cooling temperature of 150-50 C. EFFECT: provided safety in process conduction, reduced material and power consumption. 1 tbl, 1 ex
