Dielectric Properties of Spark-Plasma-Sintered Strontium Niobates

Abstract:

We have successfully prepared dense (Sr,Ba)2Nb2O7 ceramics consisting of fine microstructures by the combination of using double metal alkoxide as the precursor for synthesis of strontium barium niobates and applying the spark-plasma-sintering processes. Phase-pure orthorhombic (Sr1-xBax)2Nb2O7 was obtained in the range of 0.8 < x < 1. The measured permittivity showed higher values compared with those of the conventionally sintered ceramics, due probably to its higher density and fine microstructures.
