In order to obtain 1 gm of Tio2 about 3.7ml of TTIV( Titanium isopropoxide precursor having 27.8-28.6% Tio2) was used and also for obtaining 1gm of Zno zinc acetate of 2.7g in 50ml is taken. Both stirred separately and later zinc acetate solution added to TTIV solution and stirred for some time. After that about 2gm NaoH in 50ml added to this mixture and stirred for some time. Washed, dried and annealed about 600c in 2 hour...after all this my Xrd results didn't have any tio2 peaks? where am i missing? A stabilizer? Any Chelatin agent? pls anyone help me out. What will be the possible reason for the Tio2 peak missing?

Yes dear, I'm afraid you miss a little tough. For that, I cited from [1] the final step before going for XRD analysis:
The ZnO/TiO2 nanocompasite particles formed were then crushed using a mortar for five minutes until the distribution of the particles making up the nanocomposite was mixed homogeneously. The fabricated particles were characterized using XRD with angle range of two thetas 20o to 80o
Hope the article is totally helpful. Best regards ….

Dear Muhammed Shajin
It's not clear to me why you expect TiO2 XRD peaks when your mixture is essentially stoichiometric for ZnTiO3.
Most likely, you made zinc titanate (1:1) and there was no TiO2 left over, and/or your reaction was incomplete but the heat treatment was not enough to grow particles to the size that would give you identifiable TiO2 XRD peaks.
Do you see XRD peaks of ZnTiO3? If not, I would guess that your particles are too small (too close to amorphous) for XRD. My advice would be to repeat the experiment and either increase the length of the heat treatment by a factor of 10 or go to 700-750 degC instead of 600. Not everything published is accurate...
Good luck!
