Hello there,
We have found CO2-Peaks on different aged clay ceramics by STA/DTA-FTIR analysis at approx. 300-400°C and 500-600°C. We found no Carbonates with the XRD. Does anyone have an idea here?
XRD analysis can not show carbon (carbon is too light element), so with this analysis you can only find CaO / MgO instead of CaCO3 / MgCO3.
We dont find any MgO/CaO in the XRD. Maybe it is thinkable that recarbonization takes place in aged / hydroxylated clay ceramics?
