FIELD: nickel carbonyl metallurgy, in particular nickel foam production.
SUBSTANCE: claimed method includes nickel deposition from carbonyl gaseous phase onto by IR-radiation heated surface of porous polymeric material (e.g., polyurethane) continuously fed in reactor followed by thermochemical treatment obtained metallized material to remove polymeric support. According to invention polymeric material is heated in stream of gas-vapor mixture, containing 6-100 % of nickel carbonyl to remove highly volatile components with subsequent polymer metallization. Structure, morphology and surface density are formed by variation of IR-radiation intensity and moving rate of polyurethane foam band. Invention is useful in production of various kind of batteries, as well as filters and catalyst carriers.
EFFECT: nickel foam of high quality and desired properties.
