  Author(s): Asad Ali*, Sarir Uddin, Abid Zaman and Zafar Iqbal
  
  Dielectric properties of (Ba0.4Ca0.6) Ti4O9 ceramic material prepared by mixed oxide solid state route were studied. X-Ray Diffraction (XRD) showed that the calcined powder of (Ba0.4Ca0.6) Ti4O9 at 900°C crystalizes in the phase of complex peroveskite type. Dielectric properties measurement was carried out by LCR meter at the range of (1 MHz to 100 MHz) and (1 GHz to 2 GHz) frequencies. The εr value of (Ba 0.4 Ca0.6 )Ti4O9 sintered ceramic sample increased with increasing frequency. In the present work, a controlled mixed oxide solid state processing route was used to prepared microwave dielectric material (Ba0.4Ca0.6) Ti4O9 and microwave dielectric properties were measured at relatively l..
