Chemical reactions of chromium and vanadium in graphite

1985/1/1In tubes coated with pyrolytic graphite, a more complex behavior was found. For the case ofV, the authors showed that V vapor was produced by thermal decomposition of VC. For Cr, however, they concluded from activation energy data and from the frequency factor of the Arrhenius plot that thermal decomposition ofCr^O^ was the rate-determining step for vapor generation.
