Notes:
Samples of pulverised fuel ash (PFA) obtained both from power stations and from laboratory combustion experiments have been examined by SIMS (secondary ion mass spectrometry) and XPS (x-ray photo-electron spectroscopy).The elemental analysis is at present semi-quantitative and indicates presence of sulphur mainly as sulphate ion in the outer surface layer (5-10 nm) of some samples. Other elements, notably Mg, Fe, K and Ti appear at higher concentrations, up to ∼ 10% once the outer 10-20 nm surface layers have been removed by ion etching.
