The results of experiments on the growth of InSb:Te by the floating zone melting in the Zona-4 setup during a flight of the Foton-3 satellite are discussed in comparison with the data on the microgravity situation typical for satellites of this type. When analyzing inhomogeneities in the crystals obtained, we reveal the frequencies corresponding to periodical variations of the impurity channel position (the facet effect), to interleaving of packs in which the growth layers are grouped, and to location of subgroups of the growth layers inside the packs. These frequencies are close to those discovered during measurements of low-frequency (quasistationary) microaccelerations (μg) onboard the spacecraft Foton-8, Foton-10, Foton-11, and Foton-12. Calculated values of μg at the place where the Zona-4 setup is installed confirm the possibility of impact of such μg on the heat and mass transfer in the melt.
