A study was conducted on the boric acid compound SrB₄O₇ to investigate the stirring conditions suitable for growing single crystals by the Kyropoulos method using stirring blades. As a result of the investigation using analytical software, when the crucible was rotated clockwise with the crystal fixed, virtual particles near the liquid surface were stagnant in the upper layer. When the crucible was rotated counterclockwise and the crystal was rotated opposite the crucible, the entire solution was agitated. We consider that the condition of providing an upward flow at the stirring blade affected the stirring of the entire solution.
