Li5Ti2O6F: a new low-loss oxyfluoride microwave dielectric ceramic for LTCC applications
Source abstract
Abstract
Use of microwave dielectric ceramics can significantly promote the development of communication devices. The primary criteria for determining their applications are excellent microwave dielectric properties and suitability for co-firing with cheap metals (e.g., Ag, Al). This study first reports the low-temperature synthesis of Li5Ti2O6F with a cubic rock salt structure. Li5Ti2O6F was prepared at 880 °C and had er of 19.6, Q × f of 79500 GHz, and τf of − 29.6 ppm/ °C. The infrared reflectivity spectrum revealed that the dielectric contribution of Li5Ti2O6F in the microwave range was mainly affected by phonon absorption. Experimental study indicated that Li5Ti2O6F had good chemical compatibility versus Ag electrode at 880 °C for 2 h. Given these characteristics, Li5Ti2O6F ceramics exhibited potential for low-temperature co-fired ceramic technology.
