    • The Role of Nanocrystallization for the Enhancement of Structural, Electrical, and Transport Properties of BaTiO3-V2O5-PbO Glasses
    Authors: Morad, Ibrahim; Harby, Amany E.; Ayoub, M. S.;  Advisor: -;  Co-Author: - (2023)

    Glass-ceramic nanocrystals (GCNs) were created via annealing at crystallization temperature Tc for the parent BaTiO3-V2O5-PbO glasses prepared by the melt quenching technique. The amorphous character of the existing quenched glasses was confirmed by scanning electron microscopy. Furthermore, the general characteristics of x-ray diffraction support the amorphous nature of the glasses. In the related heat-treated samples, the typical nanostructure size is less than 60 nm. It was discovered that an increase in the density of the GCNs occurred with an increase in the BaTiO3 percentage. Also, with increasing BaTiO3 content, a slight increase was observed in the crystallization and glass transition temperature from 335°C to 365°C and 265°C to 320°C, respectively.
