I have prepared TiO2 nanomaterial in which I got both anatase and rutile phases. I want to calculate the amount of anatase and rutile phases present in that. Please suggest how I can calculate the phases?
You can measure the ratios of highest intensity peaks of both the compounds from XRD and it gives the percentage of compounds. or you can use topas software . if it is available .
There is an alternative method to find out the volume percentage of different phases present together. For the calculation of the same, firstly, you have to identify the maximum intense peak of the phase present in the XRD pattern then find out the area under the peak for each. Then using the following formula, you can estimate phase fraction present in the sample.
Formula: phase fraction of 1st phase f1 = A1/(A1+A2+A3+...) and so on.
or f1 = I1/ (I1+I2+I3+...) and so on, where I, is intensity of most intense peak.
