Abstract
A novel aqueous solution method was used to prepare Li2MoO4 powder, which was pressed and sintered directly into ceramic pellets without any calcination or milling stage involved. Pure Li2MoO4 ceramic with the maximum bulk density of 2.898 g/cm3 (95.63 % of the theoretical value) and excellent microwave dielectric properties of ɛ r  = 5.58, Q × f = 49,328 GHz, τf = −168 ppm/°C (f = 10.17 GHz) was obtained at 540 °C/2 h. The maximum Q × f value in this work is higher than that of Li2MoO4 ceramic prepared by the conventional solid-state reaction method. The results show that the aqueous solution method is a simple and effective method to produce Li2MoO4 ceramics.
