Abstract
Procedeul de obtinere a pulberii ultrafine de zinc conform inventiei, prevede distilarea zincului la 930-960 degree C si condensarea vaporilor de zinc, cu un curent de azot, care dupa racire si desprafuire se recircula continuu în condensator. în scopul obtinerii unei pulberii ultrafine de zinc pe clase granulometrice prestabilite si cu activitate chimica marita, se alimenteaza în condensator jetul de azot echicurent cu vaporii de zinc se mentine temperatura în interiorul condensatorului la maximum 230 degree C se raceste jetul de azot evacuat din condensator la sub 50 degree C si se recircula continuu în condensator cu un debit de circa 7,5-10 m la puterea 3 N2/kg zinc.
