FTIR Spectral Characterization, Mechanical and Electrical Properties of P2O5-Li2O-CuO Glass-Ceramics

In the present investigation, X-ray diffraction (XRD), scanning electron microscopy (SEM) and Fourier transform infrared (FTIR) spectroscopy were employed to study the crystallization of (50 P2O5-50 Li2O with different CuO concentrations) glasses. Both mechanical and electrical properties were studied. The results clarified the formation of LiPO(3)phase along with Li(2)CuP(2)O(7)one which became more pronounced with successive increase in CuO contents having in mind that these phases caused measurable increase in density values. Additionally, the fracture toughness, compressive strength and elastic modulus were positively affected by the increasing of CuO contents. Moreover, DC conductivity and activation energy were also dependent on CuO contents where the latter recorded 0.56 eV for sample contained the highest CuO content. On the other hand, AC conductivity was nearly the same at low frequencies for samples had the lowest and highest CuO contents. However, in high frequencies, it showed a noticeable enhancement.

Automated summary

This study investigated the crystallization process and properties of (50 P2O5-50 Li2O) glasses with different CuO concentrations using XRD, SEM, and FTIR. The results showed that increasing CuO content led to the formation of LiPO(3) and Li(2)CuP(2)O(7) phases, resulting in increased density and improved mechanical properties. The electrical conductivity and activation energy were also found to be dependent on CuO content.
