The microwave dielectric properties of (1 - x)Nd(Co1/2Ti 1/2)O3-xSrTiO3 have been investigated. The system has been prepared by a conventional solid state ceramic method. Nd(Co1/2Ti1/2)O3 (NCT) possesses a dielectric constant (εr) of 27, a high quality factor (Q × f) of 140,000, and a temperature coefficient of resonant frequency (τff) of -46 ppm/°C. To produce a temperature-stable material, SrTiO3 (ST) has been added, which leads to a near-zero temperature variation in resonant frequency. The microwave Q × f decreases as x increases. εr increases from 27 to 29.32 as x varies from 0 to 0.1. A microwave dielectric material having εr of 29.32, Q × f of 80900, and τf of 0 has been obtained from the compound 0.9NCT-0.1ST sintered at 1440°C for 4h.
