Abstract. BaTi 2 O 5 (BT2) calcined powder synthesized by a solid-phase reaction decomposed into BaTiO 3 (BT) and Ba 6 Ti 17 O 40 (B6T17) as the firing temperature was raised. This decomposition was suppressed by adding 1 wt SiO 2 as an additive. SiO 2 did not dissolve in BT2 crystal grains and segregated as a secondary phase including Ba and Ti atoms. The incorporation of Ba and Ti into SiO
