Abstract

Here we report a new high‐Q × f and temperature‐stable oxyfluoride microwave dielectric ceramic system of Li2+xZrO3Fx (0 ≤ x ≤ 1.25) sintered at low temperatures (i.e., ≤950°C). The sintering characteristics, phase assemblage, microstructures, and microwave dielectric properties (MDPs) of the Li2+xZrO3Fx specimens were studied. The chemical bond theory calculations were employed to analyze the compositional dependence of the MDPs in the Li2+xZrO3Fx ceramic system. The optimal MDPs of εr = 15.8, Q × f = 65 100 GHz, and τf = 1.2 ppm/°C were achieved in the sample with x = 1. Besides, the ceramic samples exhibited high chemical compatibility with Ag electrodes. Therefore, the novel ceramic system of Li2+xZrO3Fx is confirmed to be a promising candidate as a low‐temperature co‐fired ceramic material. [ABSTRACT FROM AUTHOR]
