BaTiO[sub 3] single crystals were prepared by solid-state grain growth. The single crystals were obtained by seeding a polycrystalline, TiO[sub 2]-excess BaTiO[sub 3], which exhibited abnormal grain growth. The condition for single-crystal growth was essentially dependent on the grain growth behavior of the polycrystalline, sintered bodies. The annealing temperature suitable for the single-crystal growth was just below the critical temperature of abnormal grain growth in TiO[sub 2]-excess BaTiO[sub 3], which is about 1,300 C.
