Phase states and dielectric properties of solid solutions of (1–х)NaNbO3–xSr2Nb2O7, (1–х)NaNbO3–xCa2Nb2O7 binary systems

Abstract

Solid solutions of (1–х)NaNbO₃–xSr₂(Ca₂)Nb₂O₇ (0 ≤ x ≤ 0.2, Δx = 0.025) binary systems are fabricated via solid-phase reactions with subsequent sintering using standard ceramic technology. Patterns in the formation of their crystalline structure and dielectric properties are established in a wide interval of temperatures and frequencies.
