Aluminum Metaphosphate (Al(PO3)3) by XPS

The XPS spectra of aluminum metaphosphate were collected with a VSW HA150 using monochromatic Al Kα x-radiation. Monochromatic radiation provides a distinct clarity to the rich peak structure in the valence band of aluminum metaphosphate due to the absence of interfering x-ray satellites from the intense O 2s region. The valence band, survey, and the Al 2s, Al 2p, O 1s, and C 1s core levels are reported. The valence band region of metaphosphate is significantly different from that of phosphate.
