Abstract

En fremgangsmåte for fremstilling av tungmetallkarbider med høyt spesifikt overflateareal omfatter at en forbindelse av tungmetallet i gasstilstand bringes til reaksjon med reaktlvt karbon med et spesifikt over- flateareal minst lik 200 m2/g ved en temperatur mellom 900'C og 1400*C. De oppnådde rene eller blandede karbider finner anvendelse som katalysatorer eller katalysatorbærere, spesielt i forbindelse med petro- kjemiske prosesser eller i eksoskonvertere l forbren- nlngsmotorer.
