The Structural and Conductivity Characterization of P₂O₅-MgO-TiO₂-Li₂O Glass Ceramic Embedded with Nickel Nanoparticles

Abstract:

Melt quenching technique (MQT) has been used to prepare the series of 75P₂O₅-17MgO-(3-x)TiO₂-5Li₂O glasses doped Nickel nanoparticles (x = 0, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0), which was converted into glass-ceramic through heat treatment at 350 °C. In this study, the effects of NiO nanoparticle addition and heat treatment on microstructure were investigated through DTA and XRD. The frequency-dependent electrical data were used to study the conductivity mechanism. Preliminary experimental results from DTA measurement showed that the stability of the glasses are increased when the increment of TiO₂ in the glasses. The XRD results showed the completely amorphous products were prepared by MQT and crystallite structured of glass ceramic were obtained via further heat treatment. Upon the increment of temperature, conductivities increased significantly.
