I am having a bit of trouble trying to determine the amount of Silicon in a substitiuted-hydroxyapatite following my reaction. By my calculations I am expecting 0.86% Si, however XRF analysis is returning a much higher value closer to 5%.
The components of the reactions is as follows:
41mM of Si(OCOCH3)4
203mM of (NH4)2HPO4
290mM of (CaNO3)2·4H2O
Can anybody confirm what wt% of Si would be expected following this reaction?
