Although there is a formula used to calculate the cubic phase fraction and cubic volume fraction in Yttria stabilized Zirconia contains tetragonal and cubic phases, but I still need to understand the concept of this formula. Especially that I didn't find (400)t, but found (220)t instead.
For X-ray diffraction in Zirconia materials, there is one problem : if you want make some measurements youhave to consider that the penetration of X-ray in this material is low. And at the second the main problem is precisely the polymorphism of zirconia, which it makes difficult the identification of polymorphic phases. if you will read in lecterature you will find a lot of different information about this. only an expert eye with a normal instrument is able to sense the presence of polymorphic phases.
But the formula that you have reported above is for GIXRD?
can you write this formula?
What kind of intrument do you have?
I use the formula of Xc= (I(400)c)/(I(004)t + I(400)t + I(400)c) to calculate the volume fraction of cubic phase over tetragonal (if we can confirm that no monoclinic phase exists). The signals for all the three peaks are much weaker than (111)t/c, so you need to do a fine scan with narrow 2_theta (70~80) to identify the them.
