Abstract	AY(2)Si(3)O(10) (A = Sr, Ba) trisilicate ceramics were synthesized by traditional high temperature solid state reaction method. X-ray diffraction patterns and Rietveld refinement revealed that AY(2)Si(3)O(10) (A = Sr, Ba) ceramics belonged to triclinic and monoclinic crystal systems with Pi and P2(1)/m space groups, respectively. The vibrational modes of [SiO4] tetrahedra, [YO6] octahedra and [(Sr/Ba)O-8] polyhedra were analyzed by Raman spectroscopy. The infrared spectroscopy fitting analysis was used to determine intrinsic dielectric properties. Excellent microwave dielectric properties were measured for SrY2Si3O10 and BaY2Si3O10 with epsilon(r) = 9.3, Qf = 64100 GHz, tau(f) = 31 ppm/degrees C and epsilon(r) = 9.5, Qf = 65600 GHz, tau(f) = 28 ppm/degrees C, respectively. Both trisilicate ceramics are considered potential candidates for 5G and mm wave technology, provided tau(f) can be further tuned.
