摘要：
New temperature stable 4 wt% LiF-doped (1-x)Li2Mg3TiO6-xSrTiO(3) (LMT-ST, x = 0.05, 0.08, 0.10, 0.15) composite ceramics were fabricated by solid-state reaction for low-temperature co-fired ceramics (LTCC) applications. Well-densified LMT-ST composite ceramics were obtained with a relative density of 97.2% at 900 degrees C. A near zero of tau(f) value was obtained by tuning ST composition. 0.9LMT-0.1ST-4wt% LiF ceramics displayed optimum microwave dielectric properties: epsilon(r) = 19.5, Qxf = 64290 GHz, tau(f) = 6.5 ppm/degrees C at 900 degrees C. Such samples were compatible with Ag electrodes, which suggests suitability of the developed material for LTCC applications in wireless communication systems. (C) 2017 Published by Elsevier B.V.
