That there is nevertheless a transport can be related to the presence of a partial pressure gradient of SiCl2, which can disproportionate into Si and SiCl4. 16. 16) In considering this example the distinction between reversible and irreversible solubility (of a solid in the gas phase) becomes clear. 13. , by lowering the temperature, gives the amount of silicon that is irreversibly dissolved in the gas phase. SiCl4 is the solvent and does not, despite its silicon content, contribute to the reversible solubility of Si(s).
Thus, the number of gaseous species that will have an impact on the transport of ZnO by chlorine rises to four. 11). 4). p*(X)] for the considered gas species yields only for Cl2 a negative value; Cl2 has to be regarded as transport agent. The positive values for w(ZnCl2) and w(O2) correspond to their role as transporting species. Furthermore, for atomic chlorine a positive transport efficiency w(Cl) is obtained. The two required unique reaction equations have to be set up in a way that gas species with negative value for their transport efficiency occur as educts.
An extensive thermodynamic treatment will not always be necessary. For a more detailed understanding, however, this chapter will provide a survey of models that will allow a quantitative description of the observations made over the course of a transport experiment. These models will provide an understanding of how the gas phase relevant for the transport has been formed, which temperature gradient will be suitable, which condensed phases will be deposited, and if possibly deposition of polyphasic solids in the sink has to be anticipated.
