Abstract
A thermodynamic study of the process of close-spaced chemical transport of nickel ferrite with tellurium tetrachloride has been carried out. On the basis of computed data on the partial pressures of the species in the transport system, the temperature dependence of the change in the conversion degree of the transport reaction and of the supersaturation in the crystallization zone were plotted and used to determine the optimum experimental conditions. Stoichiometric nickel ferrite crystals with maximum edge dimensions of 5 mm were obtained.
