The Scherrer equation is used to determine crystallite sizes from XRD spectra.
they contain K, a shape factor, that varies from 0.89 for spherical to 0.94 for cubic particles. Usually, this is set to 0.9 for particles of unknown size.
Does anyone know where we could find a table with the exact...
Hi All,
I am new in this forum. Is anybody who can guide me about the Peak Matching of XRD Analysis. I am looking for the peaks of ZnO.
Thanks and Regardss
I use to do XRD from room temperature to High temperature and then cooling again at room temperature.
I see there is constant going to the right for all the peaks and also their intensities are decreasing, also the width of peaks is becoming larger.
I would like to interpret those data and also...
Hi everybody,
we are looking for powder XRD purchase to our University. Is anyone tell me what firm is better, what kind of accessories to purchase? I heard that Panalytical made some device for nanomaterials size measurements. Anybody knows how does it works and is this good?
Thanks a lot.
Im Jessica , I got an xrd pattern that i can't figure it out. Can you guys help me to find out what it is :!):shy::cry: or can anyone give me some idea what kind of material this is.(Apart from it's an amorphous.)
Hi everybody
Actually i need to calculate a cristallite nanoparticles size by using my XRD measurement results. I looked in some sites and published papers, folks are used an equation called Scherrer equation to calculate the radius of a nanoparticle. I've found in an another forum this...
Hi guys,
I have an question about the correlation between grain size caculated from debye-scherrer and the AFM results for my AlN epi layer samples.
From my AFM results, the trend of grain size of three samples are getting smaller( around 200-10 nm range among three samples). but the FWHM of...
I want to characterise a coal char particle of size 6 to 15 mm using XRD. I am aware of powder XRD being done. But I want to subject the sample as it is as a lump particle. Is any such XRD possible. Will the XRD results of lumped sample differ from that of the powder sample? Please explain...
the XRD pattern of Zinc oxide and zinc oxide in acrylic acid !
I did XRD analysis of zinc oxide, and its peaks are at 31.7, 34.4, 36.2, 47.5, 56.6, 62.9 and 67.9 (2-theta degree).
further, I did XRD of zinc oxide dispersed in acrylic acid/IPA. but it's weird ! Why I could got some peaks at...
Hello,
I came to this forum looking for an answer to a pretty simply question about the Scherrer equation for peak broadening in the XRD pattern.
I understand that the full-width-half-maximum of the peak must be in radians, but when I measure the FWHM, it is in 2 theta. Do I need to half...
Hi, the XRD in question is a Siemens (Bruker-Axs) D5000 and apologies as this may be a somewhat long post.
A member of staff tried to change password permissions on our XRD Crystallite Size software (Win-Crysize) and the copyright dongle for the software didn’t like this, so we now have a...
Hi friends,
What is the best way to analyze the XRD data for phase identification and particle size calculation? so far I am using debye-scherrer's formula. Is there any advanced formula?
thankyou
