Phase pure Na2Zn5(MoO4)(6) ceramic is prepared by solid state ceramic route and the structural characterisations have been done using powder X-ray diffraction and laser Raman spectroscopy. Na2Zn5(MoO4)(6) ceramics exhibited a maximum density of 3.73 g/cm(3) at 590 degrees C together with epsilon(r) = 8.1, Q(u) x f = 35,800 GHz and tf = -95 ppm/degrees C at microwave frequencies. Scanning electron micrographs of the sintered samples show exaggerated grain growth, which is correlated with the microwave dielectric properties. The chemical compatibility between Na2Zn5(MoO4)(6) ceramic and metal electrode has been ascertained using energy dispersive X-ray spectroscopy. (C) 2017 Acta Materialia Inc.
