- W1969137783 abstract "Abstract Single-phase Ba 2 Ti 9 O 20 materials, which are free from secondary phases have been successfully synthesized by using inverse micro-emulsion process. Although the BaTi 5 O 11 phases were resulted preferentially when the as-prepared powders were calcined (800–1000 °C, 4 h), they can be converted into Hollandite structure (Ba 2 Ti 9 O 20 ) after sintering the samples at 1200–1300 °C (4 h). The prime factor facilitating the formation of Hollandite phases in micro-emulsion process is presumably the atomic scale mixing of cationic species with proper proportion. Dielectric constant measured at 7 GHz varies insignificantly with calcination and sintering conditions for the sample possessing a density higher than 94% T.D. In contrast, the Q × f value increases with the density of the samples provided that no abnormal grain growth phenomenon has occurred. The best microwave dielectric properties obtained are K =39 and Q × f =22,000, which corresponds to the 1250 °C×4 h sintered samples prepared from 900 °C-calcined." @default.
