Pure Phase Ba2Ti9O20 Powders Prepared by Conventional Processing

Abstract

Abstract: Pure Ba₂Ti₉O₂₀ powder was prepared by using traditional ceramic technological process with BaTiO₃ and TiO as the starting raw materials. In order to explore
the phase development sequence, the mixed powder of BaTiO₃ and TiO₂ was calcined with different temperatures from 800℃ to 1150℃ and different keeping
hours from 1/60 to 64h, then identified by X-ray powder diffraction. The results show that the pure phase of Ba₂Ti₉O₂₀ can be obtained at 1000～1150℃/4～32h,
and the homogeneity of the constituents is an important processing factor for obtaining pure Ba₂Ti₉O₂₀ powder.

Key words: solid reaction, pure Ba₂Ti9O₂₀, homogenization
