### Abstract

The microwave dielectric properties of (1 - x)Nd(Co_{1/2}Ti _{1/2})O_{3}-xSrTiO_{3} have been investigated. The system has been prepared by a conventional solid state ceramic method. Nd(Co_{1/2}Ti_{1/2})O_{3} (NCT) possesses a dielectric constant (ε_{r}) of 27, a high quality factor (Q × f) of 140,000, and a temperature coefficient of resonant frequency (τ_{f}f) of -46 ppm/°C. To produce a temperature-stable material, SrTiO_{3} (ST) has been added, which leads to a near-zero temperature variation in resonant frequency. The microwave Q × f decreases as x increases. ε_{r} increases from 27 to 29.32 as x varies from 0 to 0.1. A microwave dielectric material having ε_{r} of 29.32, Q × f of 80900, and τ_{f} of 0 has been obtained from the compound 0.9NCT-0.1ST sintered at 1440°C for 4h.
