Radiation stability study on cerium loaded iron phosphate glasses by ion irradiation method
- 20 Downloads
To study radiation stability of iron phosphate glasses, cerium is used as surrogate of actinides. Cerium doped iron phosphate glasses have been synthesised. Heavy gold ion irradiations have been performed on pure and cerium doped iron phosphate glasses to mimic ballistic damage due to cascade of recoil atoms. Pure and cerium doped glasses are irradiated with gold ions of energy 750 keV at fluence of 2 × 1015 ions/cm2. In this paper, ion irradiation effects on glass network modification and change in speciation of network former have been discussed. Significant changes in glass network structure and speciation of network former is observed.
