It is very difficult to predict. I recommend to dry the sample well and repeat the measurement.

Hi,

It can not be Al even though the diffraction patterns are coming in the same range as Al. The intensity of Al's patterns is totally opposite to this. You may have to match the library data to get the exact match. It's really hard to tell bey looking at the patterns.

Good luck.

Thank you.

In case you know that only Al or Al2O3 can be the phase, and the radiation is Cu, then it is definitely Al. The different intensities can be easily interpreted by an existing cube texture caused by the processing of the sample.

In case you are asking why... There is a small but still effective software called PowerCell which enables the simulation of diffraction patterns within tens of seconds... You can download is here from Researchgate.

Thanks Nolze,

From where I can download PowerCell

Kapil Bhatt

here is a link to PowderCell:

ftp://ftp.bam.de/Powder_Cell/

you should download the file 'pcw23.exe'...

good luck!

Hi, a better option than the ftp link (thanks V. Sidey) is https://www.researchgate.net/project/PowderCell-a-useful-tool-for-crystallographers-mineralogists-and-materials-scientists

The reason I do not exactly know which version is downloadable via ftp. Moreover, the link also contains a description which might be useful in case you want know more about the background equations and procedures used in PowderCell.

Gert Nolze just in case, the ftp version is 2.4 exactly... anyway, thanks for the link...

I guess you have strong texture in your sample, rotating sample helps in elevate other peaks. play with acquisition time.

good luck

I have got the answer for this question. The first peak corresponds to aluminium oxide and second and third for aluminium.

Thanks to everyone and those who follows this question please refer to the attached literature for details.
