Abstract

The effect of halide ions on density, electrical, magnetic and crystallization kinetics for (20X–50P 2O 5–30V 2O 5) mole% has been investigated, where X=CaO, CaF 2, CaCl 2 and CaBr 2. Halide ions reduce the glass transition temperature, crystallization temperature and activation energy of crystallization. Density, electrical conductivity and magnetic susceptibility increase while molar volume, glass thermal stability and interatomic distance between transition metal ions decrease as the halide ions replace the oxygen ions in these glasses.
