Complete solid solutions between Mg 2 SiO 4 and LiMg PO 4 are confirmed by the XRD results. The phase constitution of 0.5Mg 2 SiO 4 ‐0.5LiMg PO 4 is found to be dependent on firing temperature. The chemical compatibility between Mg 2 SiO 4 and rutile phase at sintering temperature is modified by incorporating LiMg PO 4 . The microwave dielectric properties of (1− y )(0.5Mg 2 SiO 4 ‐0.5LiMg PO 4 )‐ y TiO 2 ( y = 0–0.3) composite ceramics have been investigated. The optimized microwave dielectric properties for 0.35Mg 2 SiO 4 ‐0.35LiMgPO 4 ‐0.3TiO 2 ceramics sintered at 1050°C show low dielectric constant (11.4), high‐quality factor (31 800 GHz), and low‐temperature coefficient of resonant frequency (−4 ppm/°C).
