Abstract: BaNb(2-x)TaxP2O11 (x = 0, 0.5, 1, 1.5 and 2) ceramics were prepared by the conventional solid state ceramic route. The relative permittivity (er) of the ceramics decreased from 25.3 for x = 0 to 12.9 for x = 2. BaTa2P2O11 (x = 2)sintered at 1250 C showed good microwave dielectric properties with Qu 9 f = 28,900 GHz and sf = - 29 ppm/ C.The addition of 5 wt% TiO2 lowered the sintering temperature to 1225 C and improved sf to -6 ppm/ C with er = 13.4 and Qu 9 f = 17,200 GHz
