Annotation: Recently, the trend of growing single crystals is unidirectional growth, where the growth of the crystal takes place from large-area seeds in one growth direction c, which homogenizes their structure, and thus improves superconducting properties. The project deals with the possibility of preparing large-area seeds, usable for the preparation of samples by the SDMG method (growth of a single crystal from below in one growth direction). Since the samples prepared by the SDMG method copy the structure of the seed, for the production of large-area seeds there is a need to optimize the time-temperature regime, with the aim of efficient preparation of seeds of high quality, with an appropriate structure and composition, and with the minimum of structural defects. The repeated use of large-area seeds requires an increase in the plasticity of such samples, which can be achieved by adding silver, thus preventing the formation and propagation of cracks in the seed during cyclic thermal loading.
