The effect of excess Li + (d) on microstructures and microwave dielectric properties of Ca 0.16 Sr 0.04 Li 0.4 Nd 0.4 TiO 3 ceramics with d = 0.00125-0.0125 was investigated. XRD analysis showed that lattice parameters in a-axis, b-axis, and c-axis became longer by the addition of small amount of excess Li + . Ca 0.16 Sr 0.04 Li 0.4 Nd 0.4 TiO 3 ceramics with d = 0.0075 after being sintered at 1270°C showed the optimal values with e r = 138, Q.f = 1591 GHz, and s f = 52 ppm/°C. Impedance measurement indicated that the grain regions showed the inhomogeneity in electrical properties and dielectric loss of the ceramic system were mainly derived from the semiconducting grain cores.
