Critical study of the application of vold's theory to the determination of reaction enthalpies from DTA traces

摘要: Abstract Many authors have concluded that the decay of a DTA curve to base line is described by Newton's cooling law beyond point at which reaction complete and this means plot differential temperature against time gives straight with slope equal thermal conductivity sample + crucible thermocouple. The present work shows because kinetic reasons, linear logarithm versus (or temperature) obtained even if still in progress. Hence, Vold's method cannot be used all for determining heats.
