The novel ultra-low temperature sintering (1-x)Na(2)Mo(2)O(7-)xNa(0.5)Bi(0.5)MoO(4) ceramics have been obtained via solid-state reaction method for passive integration use. The Na2Mo2O7 and Na0.5Bi0.5MoO4 crystal phases are found to be compatible with each other from the results of XRD and SEM-EDS. With the x value changing from 0.36 to 1.00, the epsilon(r) increases from 16.0 to 32.0 and the tau(f) value varies from -58 to 47 ppm/degrees C. At x = 0.75, the 0.25Na(2)Mo(2)O(7)-0.75Na(0.5)Bi(0.5)MoO(4) ceramic sintered at an ultra-low sintering temperature of 580 degrees C can be densified ( > 96%) and possesses good microwave dielectric properties of an epsilon(r) of 24.0, a Q x f value of 13,000 GHz (at 6.2 GHz), and a tau(f) value of 3 ppm/degrees C. The theoretical epsilon(r) and tau(f) of the (1-x)Na2Mo2O7-xNa(0.5)Bi(0.5)MoO(4) composites were calculated using the mixing law and in accordance with the measured values.
