ABSTRACT (Sr0.8Pb0.2)TiO3-MgO (5050 by weight) composites are fabricated and their dielectric properties are investigated at room temperature in the frequency range between 10 kHz and 26 GHz. Relative dielectric constant is ∼116. tan δ at 10 kHz is 0.0005 or less than 0.0005, but tan δ at higher frequencies increases to 0.006 at 4 GHz and 0.04 between 18 GHz and 26 GHz.
