The microwave dielectric properties and the microstructures of Nd(Co1/2Ti1/2)O-3 (NCT) ceramics using starting powders of Nd2O3, CoO, and TiO2 prepared by the conventional solid-state route have been researched. The dielectric constant values (epsilon(r)) saturated at 24.8-27. Quality factor (Q x f) values of 37900-140 000 ( at 9 GHz) and the measured tau(f) values ranging from -45 to -48 ppm/degrees C can be obtained when the sintering temperatures are in the range of 1410 degrees-1500 degrees C. The epsilon(r) value of 27, the Q x f value of 140 000 ( at 9 GHz) and the tau(f) value of -46 ppm/degrees C were obtained for NCT ceramics sintered at 1440 degrees C for 4 h. For applications of high selective microwave ceramic resonator, filter, and antenna, NCT is proposed as a suitable material candidate.
