On the basis of thermodynamic analysis of reactions with the participation of elemental halogens and halogen-containing compounds, it was established that chlorine and especially carbon tetrachloride are suitable agents for the chemical transport of tin dioxide. The results of thermodynamic analysis are confirmed by experiments on SnO₂ single-crystal growth. In the presence of CCl₄, well-shaped cassiterite crystals with a maximum size of about 3 mm are obtained. Their light yellow color shows a deviation from the stoichiometric composition.
