Hi everyone,
I have conducted an xrd on the waste tyre crumb rubber particles. It shows an amorphous hump centred around 20 degree two theta, few Zinc Oxide peaks and another two peaks (around 29-30 degree two theta and 43 degree two theta). I have identified these peaks as Zinc Phosphorus Sulfide but i am not too confident if the Zinc Phosphorus Sulfide is the correct identification. Could somebody help me with these peaks (i) 29-30 degree two theta and (ii) ~43 degree two theta?. I have attached a screenshot of peak identification and the .raw file. Our XRF equipment is out of order so i did an EDS analysis to identify the elements present, i have attached the screenshots of that as well. EDS shows the presence of (Na, Si, O, S, Fe, P, Al, Ca).
Hi Niloofar,
For peak identification i'm using Brukers Diffrac.Eva with PDF commercial database
Hello, this looks like it is mainly Zink Oxide, Calcium Carbonate and Carbon (black).
Thanks Degen,
I was bit suspicious about CaCO3 earlier when i was going through the search/match, but with your confirmation and literature search on tyre rubber, i am much confident with this identification now.
