摘要
FIELD: process engineering.;SUBSTANCE: invention relates to powder metallurgy. It can be used in production of pyrotechnic fuses, as gas absorbers in vacuum tubes, lamps, vacuum hardware and gas cleaners. Oxide of basic element selected from Ni, Zr and Hf is mixed with alloying metal powder selected from Ni, Cu, Ta, W, Re, Os or Ir and with reducing agent powder. Produced mix is heated in kiln in atmosphere of argon to initiation of reduction reaction. Reaction product is leached, flushed and dried. Said oxide of basic element features mean particle size of 0.5-20 mcm, BET specific surface of 0.5-20 m2/g and minimum content of said oxide of 94 wt %.;EFFECT: powder with reproducible combustion time, specific surface and distribution of articles in sizes and time.;23 cl, 5 ex
