FIELD: metallurgy.
SUBSTANCE: composite material of carbon-nickel system is produced by application of the metal active component in form of solution of nickel azide on porous carbon base, its porous impregnation through full volume with further restoration by hydrazine hydrate to metal nanosize nickel in high alkaline medium at pH ≥12 and temperature 90-100°C. As the carbon base the porous coal matrix with volume of micro- and mesopores 0.31 cm3/g and 0.43 cm3/g, respectively, and specific surface 1113 m2/g. Size of nickel particles in the micropores is 2 nm, in mezopores - 3-15 nm, and on matrix surface and in interporous volume 80-150 nm.
EFFECT: invention simplifies process of high pure composite material production.
