| Abstract Scope |
Technologies which are currently used for the production of single crystals are accompanied by many problems, such as high costs of production. However, recently it has been shown that many of the challenges associated with the growth of single crystals can be overcome by solid-state single crystal growth (SSCG) from polycrystalline materials. In this work, Y3Al5O12 (YAG) single crystals were grown by the SSCG method using spark plasma sintering (SPS). The powder containing the seed crystal was sintered using SPS and the single crystal was grown through the conversion of the polycrystalline matrix. XRD analysis showed that the polycrystalline matrix had a single cubic YAG phase. From the SEM images, large areas without grain boundaries and small porosity, described as single crystals, could be observed. Furthermore, the growth kinetics and mechanisms of SSCG of YAG prepared by SPS was discussed. |
