摘要：

The traditional solid-state sintering method was employed to prepare Li 3 Ba 2 Ln 3 (MoO 4 ) 8 (Ln = Gd, Tm) ceramics, and the impact of firing temperature on the structure, microstructure and microwave dielectric properties of the novel molybdate Li 3 Ba 2 Ln 3 (MoO 4 ) 8 (Ln = Gd, Tm) ceramics was examined. XRD and Rietveld refinement outcomes validate the monoclinic system with the C2 / c space group for Li 3 Ba 2 Ln 3 (MoO 4 ) 8 (Ln = Gd, Tm). For the Li 3 Ba 2 Gd 3 (MoO 4 ) 8 ceramic sintered at 800 degrees C, a e r is 9.42, a Q x f is 16,988 GHz, and a ti f is 4.57 ppm/ degrees C. The Li 3 Ba 2 Tm 3 (MoO 4 ) 8 ceramic sintered at 800 degrees C has a e r of 9.74, a Q x f of 25,401 GHz, and a ti f of 1.08 ppm/ degrees C. XRD and EDS analyses prove the good chemical compatibility of the co-sintered Li 3 Ba 2 Gd 3 (MoO 4 ) 8 ceramic with the Ag electrode. Therefore, the Li 3 Ba 2 Gd 3 (MoO 4 ) 8 ceramic is suitable candidate material for LTCC applications.
