This technique provides high chemical and microstructural homogeneity as well as low porosity. Glass samples were subjected to either single or double heat treatments, between 700 °C and 1000 °C, in order to obtain the glass-ceramics. Differential Scanning Calorimetry - DSC - results evidenced the possibility of fabricating these ceramics from glass in the system Li2O·Al2O3·TiO2·P2O5. Samples observed by Scanning Electron Microscopy - SEM - showed a finely grained microstructure which was homogeneously distributed and non-porous. X-ray Diffraction - XRD - patterns showed the formation of the high conducting phase LiTi2(PO4)3. A high ionic conductivity, in the order of 10-3 S/cm at 1000 °C, was measured by Impedance Spectroscopy - IS. It suggests that the synthesis method used in this research is useful for fabricating lithium ion glass-ceramics and opens up a new alternative for manufacturing different electrical ceramics. 2018 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49657889019 https://www.redalyc.org/journal/496/49657889019/ https://www.redalyc.org/journal/496/49657889019/html/ https://www.redalyc.org/journal/496/49657889019/49657889019.epub https://www.redalyc.org/journal/496/49657889019/movil 10.15446/dyna.v85n205.70273 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.205 Vol.85 |
