The Mg3(PO4)2 ceramics were prepared by using the conventional solid-state reaction method. And the samples sintered at 1025 °C showed high relative density with 96.51 %. The crystal structure and dielectric properties of Mg3(PO4)2 ceramics were investigated. Optimized dielectric properties tested at 1 MHz were obtained in Mg3(PO4)2 ceramic sintered at 1025 °C for 2 h (εr ~ 5.9, tanδ ~ 0.0015 and τε ~ 40 ppm/°C). Meanwhile, Mg3(PO4)2 ceramic showed the chemical compatibility with Ag electrodes, which can be a promising candidate for multilayer components applications in high frequency.
