Manan, Y. Iqbal] New dielectric ceramics in the SrLa4−xSmxTi5O17 (0≤x≤4) composition series were prepared through a solid state mixed oxide route to investigate the effect of Sm+3 substitution for La+3 on the phase, microstructure and microwave dielectric properties. At x=0-3, all the compositions formed single phase ceramics within the detection limit of in-house X-ray diffraction when sintered in the temperature range 1500-1580°C. At x=4, a mixture of Sm2Ti2O7 and SrTiO3 formed. The maximum Sm+3-containing single phase ceramics, SrLaSm3Ti5O17, exhibited relative permittivity (εr)=42.6, temperature coefficient of resonant frequency (τ f)=−96ppm/oC and quality factor (Q u f o)=7332GHz. An analysis of results presented here indicates that SrLa4−xSmxTi5O17 ceramics, exhibiting τ f~0 and εr~53 could be achieved at x~1.4 but at the cost of decrease in Q u f o.
