Abstract
In order to get a microwave dielectric ceramics having near zero τƒ, different ratio of ZnTiNb2O8 and SmTiNbO6 powders are sintered together at different temperature. XRD and SEM of these composite ceramics are tested to analyze the composition. The microwave properties and density of the composite ceramics are measured in order to find the best ratio of ZnTiNb2O8 and SmTiNbO6. For (1-x)ZnTiNb2O8-xSmTiNbO6 ceramics, the ceramics have very good microwave properties(εr = 24.63, Q*ƒ=11846GHz, τƒ = 0.16ppm/℃) when x is 0.35.
