Low-temperature-sinterable (Zr0.8Sn0.2)TiO4 powders were prepared using 3 mol% Zn(NO3)2 additive and then compared with powders prepared using 3 mol% ZnO additive and no additives. Sintering at 1200°C for 2 h produced a dielectric ceramic with ρ= 98.6% of theoretical density (TD), ɛr= 38.4, Q×f (GHz) = 42000, and τf=−1 ppm/°C. Sintering at 1250°C resulted in an excellent dielectric with ρ= 99% of TD, epsilonr= 40.9, Q×f (GHz) = 49000, and τf=−2 ppm/°C. Scanning electron microscopy showed a microstructure with grains measuring 0.5 to 1 μm, and transmission electron microscopy revealed secondary phase in the grain boundaries.
