The required database is ICDD/JCPDF/PCPDF available.

Dear Sampriti, 

Please have a look at the RRUFF project by clicking on the following link:

COD? 

For mineral: AMCSD

Thank you Dinesh, Masoud and Gert. 

But ICDD is not free.

Regarding AMCSD and COD, I am not able to use the match option. Since I have little idea about the mineral phases in my sample, so can I deposit the 2 theta values that I have, and get  back the possible minerals present in it by matching with database?

I am attaching XRD spectrum data of one of my samples (It's of Ipomoea carnea, a weed). Can anyone please help to find out the mineral phases in it?

Thanks.

Sampriti.

Hi Sampriti Kataki, What kind of anode did you use to obtain the XRD data?. If you know the wavelength I will try to help you.

Hello Erdenee, it is Cu K-alpha with wavelength  0.15418 nm. I would be grateful if you can please help me.

Thank you.

Have you performed an elemental analysis to determine at least the main elements present in your sample? Otherwise it could be impossible to proceed with the phases identification  

Thank you Marcella.

Yes, I have the performed ICP and EDX analysis of the sample. It shows presence of C, H, O, N, P, K, Cu, Fe, Mn, Zn, Ca, Mg, Fe, S, Al, Si mainly.

I see that you have many elements so it could be very difficult to find all the phases. I think that you have also tried with silicates, carbonates and oxides, the most plausible phases. You have many possible combinations of elements so I think that you should proceed for attempts. Maybe in the next days I can take a look at your pattern (now I have some problems with the software)  

Yehh Marcella, I understand. There are many possible combinations considering large number of elements present. Moreover, my sample is a biomass sample, so it will have number of phases.

However, I just need to find out the most prominent mineral phases, though not all.

It will be really appreciated if you can please help me out.

Thanks.

Sampriti.

I normally use JCPDF. Others are there.

Hello Sampriti Kataki, I use "Crystal Impact Match" program which accesses to ICDD, ICSD and COD databases in order to make qualitative phase analysis from powder diffraction data. You can download the COD database and "Crystal Impact Match" program from below link:

I hope it will help you. Good luck.

fpsm.radiographema.com

runs a match with the entire COD database, unless you are willing to provide the most prominent elements. Hope it helps

Here found a additional tool, find the attachment.

X'Pert Data as a software is good but you can also engage web of MinDat https://www.mindat.org/

Hello all. Heshan Galagedara could you send me PDF2 database link? Thanks. [email protected]

Tarik Kabak ... here's a link for free download

Good Luck

Link will be helpful to smooth XRD data by removing signal noise
