Abstract
A novel low-loss La 5 Sn 4 O 15 ceramic is fabricated via traditional solid-state route. The investigation mainly focused on phase composition, dielectric characteristics and crystalline from 1300 to 1400 °C. The XRD analyses confirmed the La 5 Sn 4 O 15 ceramic is consisted of cubic and hexagonal structure. The effects of relative density on the Q × f and permittivity are also investigated. The satisfactory properties (ε r of 17.4, Q × f of 84,760 GHz and τ f of −19.08 ppm/°C) are obtained at optimum sintering condition (sintered at 1350 °C for 4 h), indicating La 5 Sn 4 O 15 ceramic is a promising ceramic for using in wireless applications region.
