I would like to ask another question, after masking one or two points, how much the reliable calculation is? Will it not affect the reliability of results when two points are excluded?

[@SAYPhysics]

It totally depends on the flexible range of your sample. Of course, accuracy of the measurement is compromised, depending on the total set of measurements (acquired data points). Thanks

[@qmtv5772]

Dear Dr. I would like to ask, in UDEDM, what value of Y did you put it? Because each hkl has its own Y value, which hkl's Y value did use or did you use average?

Please check in the video description where I have mentioned the respective reference thay explains all these values. Thanks

Dear professor, First of all I would like to congratulate you for the explanation. However, I would like to ask you a question. I am wanting to calculate the crystallite size for an amorphized sample, but the data from the XRD calculation in origin program does not converge. How do I do this? Do you have any suggestions?

[@SAYPhysics]

Thanks for the appreciation dear 😊. I have no idea for such a situation. As a suggestion, you may go through some threads in ResearchGate or .can ask a new question there. I hope, you will find some clues. Thanks

[@ayeshazulfiqar3498]

Sir.... I got different crystallite size values by WH plot method (11.58nm) and by scherrer plot method (15.12nm ).....is it wrong or is it possible to get different values?

[@SAYPhysics]

Both work in different scenarios. I'll suggest to carefully watch the presentation in the beginning of the videos, which will guide you about your data. Thanks

[@universeman80]

Thank you, dear teacher. If the non-hexagonal crystalline element, for example, is a cube or quadrant, the same equations we use And thank you very much.

I have a question plz answer that. I have data for pure nickel, 4 peaks of 111, 200, 220 and 311 , but when i am calculating crystallite size and strain using W-H plot, after masking one data, adj R square value is coming around 0.85, but there is lot of error. for different parameters, intercept is coming same for all, but strain coming different, how is that possible?? and is scherrer equation more reliable here ?

[@SAYPhysics]

It seems that your data pre treatment is to be addressed first. As both the Scherrer equation and WH are peak width dependent, so, you will have to make it sure first that there are no other contribution to the peak width. I'll suggest, you go through the following playlist where I've discussed the different aspects. Thanks XRD Data Plotting and Analysis: kzbin.info/aero/PLeWSImvDbpldse8hqfvZX7MasFSkTwIIT
