FIELD: process engineering.
SUBSTANCE: invention relates to powder metallurgy, particularly, to production of open-pore nano-structured metal. It may be used in data write and store systems, various magnetic systems, as carriers of various pharmaceutical preparations for directed transfer of medicines in magnetic fields, etc. Solution of iron sulphate and nickel chloride hexahydrate salts are heated to 80-90°C. Metals are deposited as iron and nickel hydroxides by adding sodium hydroxide to solution at continuous mixing of sodium hydroxide. Then, 20-30 ml of 65 wt %-hydrazine hydrate is added to the solution and held for 5-20 minutes.
EFFECT: single-fraction mono-dispersed powder with high content of metal phase.
