Growth process of the BaTiO₃ butterfly twinned crystals was observed in the region of 1160 to 880°C by stopping the growth at different periods. The process seems to consist of two different ways, namely a relatively rapid two-dimensional growth above 1000°C and a slow thickening one throughout the crystal growth. On the other hand, growth process of the (Ba,Sr)TiO₃ butterfly crystals was also observed. The Sr content in the crystal lattice increased below 1000°C, where thickening growth is dominant. Thus the thickening growth of the butterfly crystals also shows different behaviors bounded at 1000°C. These two different growth behaviors probably originate from a large degree of supersaturation above 1000°C and a small one below 1000°C developing in the molten solution of KF-BaTiO₃. The explanations for the two growth behaviors seem reasonable referring the solubility data for the KF-BaTiO₃ system.
