Original Paper


The ceramic composites formed in the system LiTi2(PO4)3–LiF were studied by means of X-ray diffractometry, thermogravimetry, scanning electron microscopy, impedance spectroscopy, and density methods. Introduction of the foreign phase into the polycrystalline LiTi2(PO4)3-based material resulted in significant reduction of grain boundary resistance. However, a slight decrease of the conductivity could be observed when higher contents of lithium fluoride additive were present in the composite. The maximum total conductivity of ca. 3.08 × 10−5 S cm−1 was obtained for lithium titanium phosphate (LTP)–0.1LiF sample sintered at 1073 K in comparison to 5.15 × 10−8 S cm−1 for the pure ceramic LTP. The most dense material was obtained after sintering at 1073 K.
