- Abstract
La-doped CaTiO compounds with general formula CaLaTiO ( x = 0-1) were prepared via a mixed oxide solid state sintering route. X-ray diffraction analysis revealed the formation of single phase compounds with orthorhombic ( Pbnm) symmetry for x ≤ 0.25. At x ≥ 0.5, ABO type B-site deficient hexagonal perovskite phases formed along with minor secondary phases. The grain size and morphology and hence, the microwave dielectric properties varied substantially with change in dopant concentration ( x). The optimum microwave dielectric properties (ε = 45.3, Q × f = 20506 GHz and τ = −14.8 ppm/°C) were achieved at x = 0.75.
