Research Abstract |
It was found for perovskite-type oxide solid solution(Ba_<1-x> Ca_x)(Sc_<1/2> Nb_<1/2>) O_3 that the crystal structure changes in various ways with increasing x, and it is unstable and decomposes through thermal annealing with a certain range of x. Further, it was found that the microwave dielectric properties improve or degrade with the structural modulations, and the correlation between the structural modulation and the microwave dielectric properties was made clear for the solid solution.
