How can I find out if my zirconia powder is stabilized or not using the XRD pattern?
'Stabilized zirconia' in fact means 'stabilized cubic polymorph of zirconia'. Thermodynamically stable phase of the pure zirconia at the room temperature is monoclinic. The difference between these two symmetries will be obvious even without looking at the database.
Pls. find attached a file [Zoom200]: It contains:
[A]three XRD diagrams[ (i)Three forms of Zirconia,(ii)only of cubic transformation of Zirconia and (iii) stabilized Zirconia]
[B] (iv)A table containing the values of parameters of the three transformations of zirconia (v) a paragraph giving the values of parameters of stabilized Zirconia.
If both are having same structure (depends upon the temperature), you will find only a slight difference in peak position (peak shifting) and variation in intensity / FWHM. But if the structures are different, definitely you will observe a significant difference.
For stabilized ZrO2 , the XRD pattern will show cubic peaks. But for non stabilized ZrO2 the peaks will be monoclinic at room temperature. Match your peaks with JCPDS files of monoclinic and cubic ZrO2.
