Abstract

Ca substituted Sr5Ta4TiO17 ceramics were fabricated via solid state mixed oxide route. For all the investigated compositions, single phase was obtained. All the investigated ceramics crystallized into an orthorhombic crystal structure with space group Pnnm. Sr5Ta4TiO17 exhibited lower τf (~180 ppm/°C) and higher Q u f o (~8500 GHz) than its Nb analog compound (Sr5Nb4TiO17). The Ca substitution for Sr tuned the τf of Sr5Ta4TiO17 ceramics through zero and enhanced the Q u f o value at the cost of a decrease in εr value. A good combination of microwave dielectric properties i.e. εr ~49, Q u f o ~13560 GHz and τf ~−9 ppm/°C was achieved for SrCa4Ta4TiO17 ceramics sintered at 1575 °C for 4 h respectively.
