Importance Of Finding The Proper Ratio Of Alkaline Earth Oxide In A Lithium-Bismuthate-Phosphate Glass In Order To Enhance The Tailoring Of Structural And Electrical Properties

Structural features of the glass family xLi(2)O-yMgO (4.8 Bi2O3 47.6 P2O5) obtained by melt quenching technique were studied taking into account the density, FTIR and UV-vis spectra and also the electrical response observed by impedance spectroscopy. In this work it becomes clarified how the alkaline earth oxides stabilize the glassy matrix and also, the fundamental importance of determining the optimal proportion in order to obtain a flabby easily polarizable matrix to enhance the electrical behavior due to a boosted cation mobility. It is evidenced that when the glass composition becomes complex it is needed to take into account a larger number of structural parameters to understand, to predict or to design the resulting physical properties.
