Abstract
Ca0.66La0.387Ti0.88O3 microwave dielectric ceramics were prepared via a mixed oxide solid state sintering route and characterized. X-ray diffraction revealed the formation of single phase Ca0.66La0.387Ti0.88O3 ceramics with orthorhombic (Pbnm) symmetry within the detection limit of the in-house XRD facility. Raman spectroscopy revealed the presence of seven Raman active bands evident of orthorhombic symmetry, in agreement with the present X-ray diffraction results. The microstructure of sintered samples appeared almost dense with some occasional pores. Ca0.66La0.387Ti0.88O3 exhibited reasonable relative permittivity (~71.5) and quality factor (~13,407 GHz); however, its temperature coefficient of resonance frequency was high (~136.4 × 10−6/°C) for commercial applications and requires further optimization.
