A small amount of the Bi12TiO20 phase melted during sintering and assisted the densification of the specimen. The Bi2O3 and Bi8TiO14 secondary phases were found in all specimens. All the specimens that were sintered at temperatures 775 degrees C exhibited high relative densities above 98% of the theoretical density. The Qxf value of the Bi12TiO20 ceramics was influenced by the grain size. The Bi12TiO20 ceramics sintered at 800 degrees C for 5h showed promising microwave dielectric properties of epsilon(r)=41, Qxf=10400GHz, and (f)=-10.8ppm/degrees C.
