Production of zinc iron phosphate glasses by microwave and conventional processing methods
This thesis describes the production of zinc iron phosphate glasses, xZnO-(40- x)Fe2O3-60P2O5 with x = 0, 2.5, 5.0, 7.5, 10.0 (mol%) using microwave and conventional processing methods. The work aiming to investigate the potential use of microwave processing method for the production of zinc iron …

Structure and properties of iron phosphate glasses: A novel host matrix for the vitrification of high-level nuclear wastes
… and the chemical durability of vitreous binary iron phosphates of approximate batch composition 40Fe<sub>2</sub>O<sub>3</sub>-60P<sub>2</sub>O<sub>5</sub> (mol%) and those containing up to 40 wt% of one or more common nuclear waste components such as Na<sub>2</sub>O, CS<sub>2</sub>O, SrO, …

Investigation of the thermodynamics of iron phosphate melts and stability of iron phosphate glasses: effects of composition and iron redox ratio
“Iron phosphate glasses with Fe/P = 0.33 - 0.67, O/P = 3.0 - 3.5 and Fe<sup>2+</sup>/ΣFe = 0.16- 0.52 were prepared by altering batch compositions and melt conditions. Thermal analyses indicate polyphosphate glasses with intermediate chain lengths are most stable against devitrification. …

Immobilization of radioactive materials in iron phosphate glass
… study investigates the feasibility of using iron phosphate glass for the immobilization of radioactive wastes considered incompatible with borosilicate glass. Wastes may be incompatible with borosilicate glass due to high phosphorus content (Hanford tank sludges), the presence of halides …
