evaporate gas-entrapping devices. SUBSTANCE: device has nickel and BaAl4 compound; barium evaporation time is reduced due to use of two nickel powders of different morphologies first one being in essence spherical and second one, dendrite, where weight proportion between two forms of nickel may vary between approximately 4:1 and 1:2.5. Using mixtures of nickel powders of two mentioned morphologies makes it possible to reduce full evaporation time for same amount of evaporated barium by 25-30%. EFFECT: reduced activation time of device. 9 cl, 2 dwg, 1 tbl, 4 ex
