| 中文摘要 | In this two-part paper, mass transport coupled with chemical reactions in closed ampoule chemical vapor transport (CVT) of the ZnS-I-2 system is theoretically studied and numerically modeled. Part I focuses on the kinetic process of equilibrium chemical reactions and one-dimensional mass transport for the ZnS-I-2 system, which is preliminary to the two-dimensional numerical modeling of the transport process in Part II. When equilibrium chemical reactions at the two ends of an ampoule are assumed, partial pressures and mass fractions of the various species near the source and crystal surfaces are determined. By relating the diffusional mass transfer with stoichiometric chemical reactions at the interface, the velocity boundary condition for the two ends of the ampoule is established; the transport rate expression for one-dimensional diffusion/advection process is further derived, The velocity boundary condition and transport rate thus derived are applicable to general CVT and PVT processes, from simple one-component sublimation to complicated multi-component. multi-reaction processes, provided that chemical equilibrium for each process can be assumed. The theoretical values of the transport rate are calculated and compared with the experimental literature values under the same conditions for the ZnS-I-2 system. Good agreement between theoretical and experimental values is achieved for diffusion-dominated regime. (C) 2002 Elsevier Science B.V. All rights reserved. |
