Synthesis of (Pb0.45Ca0.55) (Fe0.5Nb0.5)1-xTixO3 (x = 0 and 0.1; PCFN and PCFNT) ceramics by a reaction-sintering processwas investigated.The mixture of raw materials was pressed and sintered into ceramics without any calcination stage involved. The density reaches 5.88 g cm-3(91.6% of the theoretical value) at 1270℃ for 2 h soak time in PCFN. Densification increased as B-site was substituted by 10% Ti anda density value 6.21 g cm-3 (98.1% of theoretical value) was obtained after 2 h sintering at 1270℃. Qf values of 2017 and 3331 GHz areobserved in PCFN and PCFNT sintered at 1150℃, respectively; τf of 0 and 1.5 ppm℃-1 are observed in PCFN and PCFNT sintered at1270℃, respectively.
