K 3Sb 3P 2O 14 was synthesized by microwave radiation with two kinds of reacting substances. The material was characterized by XRD,IR,TGA and characterization program. The compound crystallizes in the rhombohedral system with a =0.71 nm, c =3.08 nm, and has a layered structure with an interlayer spacing of 1.03 nm. The results of preliminary study on the mechanism of microwave radiation synthesis show that reacting temperature and velocity of solid-phase reaction were greatly affected by microwave radiation.
