METHOD OF PREPARING AFFINATED OSMIUM

摘要

non-ferrous metallurgy, particularly, affinage production of platinum group metals. SUBSTANCE: explosion-fire hazard of production process is reduced by substituting hydrogen in reducing oxidized osmium powders for mixture of ammonia with inert gas. Reduction is carried out at 1000-1100 C, and cooling is carried out to 20-30 C. EFFECT: more efficient preparation method. 2 ex, 1 tbl
