Abstract
The glass–ceramic with the composition x (LiFe5O8)/(100–x) SiO2 (x= 20, 30, 40, 50, 100 wt.%) were prepared by sol gel auto-combustion method. The influence of the SiO2 ratio in the glass-ceramics strucure prepared was investigated by X-ray diffraction (XRD) and scanning electron microscopy (SEM). Crystalline phases (LiFe5O8, SiO2, Fe2O3) were observed by X-ray powder diffraction in the glasses annealed at 800° C for 2h. The crystallite size was found to increase from 27.29 nm (x= 20%) to 91.48 nm (x= 100%). The ...
