Thermodynamik und Kinetik des chemischen Transports von Ge mit GeCl4

Thermodynamics and Kinetics of the Chemical Transport of Ge with GeCl₄ The chemical transport of germanium according to the reaction Ge + GeCl_4,g = 2GeCl_2,g has been investigated under different experimental conditions. Only for the case of large reaction volumes connected by a relatively long and narrow diffusion path the transport rate agrees with the calculated values obtained by the conventional model for diffusion between equilibrium spaces. For experiments with simple cylindrical ampouls(inner diameter 1.8cm, length 15 cm) it depends clearly upon the reaction conditions whether the inhibiting influence of kinetics or the increase in reaction rate by the thermal convection are dominating.
