Research ArticleOpen accessEffect of Niobium Oxide Incorporation on Optical Properties of Sodium Bismuth Borate GlassesHossam M. Gomaa, Saeid M. Elkatlawy, Ahmed H. El-DosokeyGlasses with the chemical compositions 60% B2O3-20% Na2O-(20-x) % Bi2O3-x% Nb2O5 (where, x = 0, 5, 10 and 15 mol. %), were prepared by fast quenching of their melts. Characteristics of the obtained solids were checked by XRD, FTIR and optical absorption spectroscopy. XRD data confirmed the amorphous nature of the glass samples. FTIR results revealed no changes in the … …International Journal of Structural Glass and Advanced Materials Research, Vol. 3, Issue 1 · 6 Jul 2019 · 7,228 accessesView PDF Cite

Research ArticleOpen accessTotal Conductivity of Calcium Iron Borate Glasses Using an Empirical FormulaHossam M. Gomaa, Saeid M. Elkatlawy, Ahmed H. El-DosokeySamples of calcium borate glasses containing iron ions have been prepared with three different concentrations of both boron and iron oxides. X-ray diffraction spectroscopy was performed and results revealed that samples are in good glassy state, with high homogeneity and short range ordered structure. Electrical conductivity was experimentally measured in the temperature range from 300 to 553 K. Conductivity results … …International Journal of Structural Glass and Advanced Materials Research, Vol. 3, Issue 1 · 21 May 2019 · 7,096 accessesView PDF Cite
