Abstract
The extended X-ray absorption fine structure method was applied to det ermine changes of the coordination parameters of Sr atoms during the t hermal conversion of Sr-contaminated brushite into calcium pyrophospha te. The results revealed that the changes of the crystallographic stru cture induced by heating are correlated with the rearrangement of the Sr environment. It was also confirmed that Sr may be used as a marker of Ca in cases of thermal conversions of orthophosphate groups into py rophosphate groups.
