Chemical Characterization of Transition Metal Spinel-Type Oxides. Part 2. Manganese-Chromium-Iron Spinels

摘要

Spinel oxides of the type formed on Advanced Gas Cooled Reactor cladding contain manganese, chromium, and iron. A range of standard spinels containing these metals have been prepared by solid state reaction of the appropriate single oxides at temperatures of 850 C and 950 C in atmospheres of CO(sub 2) or CO(sub 2)/2% CO. Each spinel series has been characterised by X-ray diffraction and energy dispersive X-ray analysis. Calibration curves relating lattice parameter to spinel composition have been produced to facilitate the identification of cladding oxides. (ERA citation 13:045451)
