Özet
The glass system having (B2O3)0.60(CaO)0.25(ZnO)0.15-x (TiO2)x, where x = 0.0, 0.025, 0.05,..., 0.15, was investigated using infrared spectroscopy, differential thermal analysis, density, magnetic susceptibility and dc electrical conductivity. The obtained IR results showed that most titanium ions exist as network former while most zinc ions exist as network modifier but boron ions appeared in different structural groups. As titanium oxide was gradually increased to 10 mol%, the glass stability, density and magnetic susceptibility increased, while the molar volume and dc electrical activation energy decreased. When titanium oxide increased from 10 to 15 mol%, the measured and the calculated properties tend to be stable. It was concluded also that the gradual increase in the molar volume acts to decrease the magnetic susceptibility and to increase the glass transition temperature.

The obtained IR results showed that most titanium ions exist as network former while most zinc ions exist as network modifier but boron ions appeared in different structural groups. As titanium oxide was gradually increased to 10 mol%, the glass stability, density and magnetic susceptibility increased, while the molar volume and dc electrical activation energy decreased. When titanium oxide increased from 10 to 15 mol%, the measured and the calculated properties tend to be stable. It was concluded also that the gradual increase in the molar volume acts to decrease the magnetic susceptibility and to increase the glass transition temperature.
