Sir why we write (a.u) in graphs e.g Intensity (a.u), is this mean approximate or please if you could clear it. Thanks!

[@SAYPhysics]

au means arbitrary units, i.e. not to scale. This unit is adopted when we don't care for the y-axis values, or when our plot is as y-offset plot, or when we plot multiple plots without caring for their intensities. Thanks

Hi Sir, I read ref I've seen almost they use Segal method. By the way, I would like to ask about Segal method calculate crystallinity index (CrI) from XRD data. 1. Do you have ref/book about how to calculate CrI from XRD data using Segal method (I mean tutorial). 2. Could you explain about how to calculate CrI from XRD data using Segal method. I've read about this method but I couldn't understand how to calculate? 3. Could you compare Segal method and this method you use in this video ? 4. When was we use this method and Segal method? 5. Which is best method to calculate CrI (I mean this method and Segal). 6. Is it method could use for almost materials (because I've seen this method use for inorganic materials, seldom use for polymer- example cellulose material) I hope I would receive yours answer soon. Thanks so much.

Hi, is the Crystallinity index & size calculated based on Sehgal method?

[@SAYPhysics]

It's a general method, not Segal's method. Thanks

[@bayanhijjawi4900]

great video, but the crystallinity of a material depends both on the intensity of the peak and the location of the peak, but in this video u only demonstrate the intensity of the peak in the calculation of the crystallinity index, though if a material diffracts after 2 alpha = 20, then this will be considered as a low crystallinity. is this true?

[@SAYPhysics]

Thanks for the appreciation. Here, in calculating the CI, we not only consider the intensity but also the FWHM (as we use area under the curve). Location of a peak in the calculation of the CI have no effect as it's the ratio of the area of crystalline to crystalline plus amorphous peaks. Thanks

[@subhamjena7059]

Sir, I have a doubt, while calculating area of peaks do we have to fix the width of area?

[@SAYPhysics]

No. As we adjust the selection for area calculation, we need not to fix it. Thanks

Hello sir..What is the range of crystallinity index for crystalline / amorphous material..? I calculated crystallinity index as 30 , Is it amorphous

There's no specific range or boundary, rather, it depends on the sample requirements. Like if we're synthesizing a single crystal, then even if few percent comes as amorphous, it's not a good sample then. Thanks

[@alexisjulianrojashuamani1582]

no sería recomendable ajustar la curva del difractograma para tener una curva más suave?

[@SAYPhysics]

Thank you for your comment! Adjusting the curve of the diffractogram to obtain a smoother curve is indeed an option that can be considered during the analysis of XRD data. Smoothing the curve can help in improving the visualization of the data and reducing any noise or fluctuations that might be present. However, it's important to exercise caution when applying smoothing techniques. The choice of smoothing parameters should be carefully determined to avoid distorting the underlying XRD peaks or introducing artifacts. Smoothing should be done in a way that preserves the integrity of the diffraction pattern and maintains the accuracy of subsequent calculations, such as the calculation of crystallinity index. Thanks

why do people keep doing this with origin? that peak there you picked is already a combined result from both crystalline and amorphous. and also for the rest of area you integrated, it all is mixed-up reflection resultants from both crystalline and amorphous. e.g. a-SiO2 and c-SiO2. it is not degree of crystallinity. you can't calculate it like that. unless there is super well-grown crystalline and the peak you chose is exclusively from that crystalline while the rest of xrd pattern represents the amorphous phase of different materials. You just can't use this in real life application. well, perhaps only for students who practice how this work.

[@SAYPhysics]

Thank you for your comment. You're right; in real-world applications, determining crystallinity can be more complex due to mixed reflections from both crystalline and amorphous phases. However, this tutorial is designed as a simplified example for students to understand the basic concept. Real-world scenarios often involve more intricate analyses, considering factors like specific material properties and phase contributions. It's crucial for learners to grasp the fundamentals before delving into more advanced applications.
