ABSTRACT. SrxZn1-xMnTiO5 (x = 0.1 to 0.9) ceramic samples were prepared by conventional solid state reaction technique. The mixed powder was calcined in the temperature range of 1050-1150oC for 10 hours. Further, the pellets were sintered finally in the temperature range 1150-1250oC for 2 hours in a crucible. The samples are characterized for dielectric properties. Especially, the variation of dielectric loss as a function of temperature and composition is discussed. The achieved results show that at room temperature all the samples reveal the low loss values which are suitable for low noise and microwave device applications. On the other hand, at high temperature all the samples perform the absorber behavior as they express high dielectric loss values.
