“…Processes of solid-state single crystal growth (SSCG) without melting of bulk starting polycrystalline material for high-melting oxides have been investigated for more than 50 years (references, for instance in [1]). Possible advantages of this method are connected with lower growth temperature, absence of expensive crucibles, uniformity of composition on great areas, which is important for preparation of doped crystals or complicated solid solutions.…”

“…Quality of the crystals obtained by SSCG depends greatly upon the quality of polycrystalline materials used, because, for instance, pores in ceramics can be inherited by the crystals [1,2]. Oxide laser ceramics developed during last years represent excellent starting material for SSCG process.…”

“…The main problems of practical application of this method were connected with very small growth rates of single crystals in the solids (usually microns per hour) and with process reproducibility. Some recent efforts using specially doped ceramics as starting materials gave new possibilities to produce single crystals of reasonable size, up to some cm in dimensions, for reasonable time, with growth velocities from hundreds microns per hour for complex perovskite-type ferroelectric oxides [1,2] up to 8 mm/h for alumina [3].…”

“…Benčan et al [53] investigated the single crystal growth of KNN and Li, Ta-doped KNN by the SSCG method. Their preparation method for the green compacts was similar to the work of Fisher et al They also used KTaO 3 as a seed crystal due to its compatibility with KNN.…”

Fabrication of single crystals has long been limited to melt-and solution-growth techniques. However, in recent years solid-state single crystal growth (SSCG) has appeared as a promising alternative to the conventional techniques due to its cost-effectiveness and simplicity in terms of processing. Moreover, the SSCG technique has enabled the fabrication of single crystals with complex chemical compositions and even incongruent melting behavior. A recently proposed mechanism of grain boundary migration known as the "mixed control mechanism" and the associated principles of microstructural evolution represent the basis of the SSCG technique. The mixed control mechanism has been successfully used to control the key aspects of the SSCG technique, which are the grain growth and the development of the microstructure during the conversion process of the single crystal from the polycrystalline matrix. This paper explains in brief basis of the mixed control mechanism and the underlying principles of microstructural evolution in polycrystalline materials and provides a comprehensive overview of the most recent research on single crystal materials fabricated via the solid-state single crystal growth technique and their properties.
