Influence of NiO Nanoparticles on Physical Properties of TiO₂ Doped Magnesium Ultra-Phosphate Glass-Ceramics

Abstract:

Tuning the physical properties of inorganic glass-ceramics through controlled doping of magnetic nanoparticles is topically challenging. A series of glass-ceramic having chemical composition 75P₂O₅-17MgO-(3-x)TiO₂-5Li₂O with x = 0 to 3 mol% containing nickel oxide (NiO) nanoparticles (NPs) are prepared by melt quenching method (MQT) via heat treatment at 350 °C. The effect of NiO NPs on thermal and magnetization response are examined. X-Ray Diffraction (XRD) pattern confirm the amorphous nature of the samples. Differential Thermal Analysis (DTA) measurement shows the decrement of glass stability from 327°C to 295°C with the increase of titanium dioxide (TiO₂) contents which are glass seem to be unstable. Significant increase in the magnetization is evidenced with the increase of NiO nanoparticles from 1.5 mol% to 2 mol%. The improved physical properties of these glass-ceramics suggest their usefulness in photo-electronic.
