XPS Interpretation of Calcium

Reasonably strong satellites are observed for CaCO 3, for example, but only weak satellites for tribasic calcium phosphate. General comments. Since calcium is a highly reactive metal, it is always present as a compound. CaCO 3 may degrade under prolonged X-ray exposure, giving CaO+CO 2.
