Abstract

AY₂Si₃O₁₀ (A = Sr, Ba) trisilicate ceramics were synthesized by traditional high temperature solid state reaction method. X-ray diffraction patterns and Rietveld refinement revealed that AY₂Si₃O₁₀ (A = Sr, Ba) ceramics belonged to triclinic and monoclinic crystal systems with Pī and P2₁/m space groups, respectively. The vibrational modes of [SiO₄] tetrahedra, [YO₆] octahedra and [(Sr/Ba)O₈] 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 ɛ_r = 9.3, Qf = 64100 GHz, τ_f = −31 ppm/°C and ɛ_r = 9.5, Qf = 65600 GHz, τ_f = −28 ppm/°C, respectively. Both trisilicate ceramics are considered potential candidates for 5G and mm wave technology, provided τ_f can be further tuned.
