Hi,

I would suggest you to perform a  quantitative phase analysis using the Rietveld method. It provides an accurate determination of the crystalline and the amorphous fractions in polyphase mixtures.

To determine the content of the amorphous phase, the sample should be diluted (in a known amount) with an internal standard which is considered as a component itself and  refined with the other phases. Once found the results for the QPA it’s important to rescale all the values to the standard amount. The difference to arrive at 100% will be your amorphous percentage.

My best,

Carlotta

Dear colleague Sadeem Fadhil,

Have a nice time and good day.

1- Glassy phases it means amorphous, glassy due glass(the example of amorphous material) the amorphous materials are characterized by one or two broad humps of XRD (see the attached file).

2- If you perform DTA or DSC for your material you can get their Tg and Tc to know the temperature at which the crystallization occurs.

3- Using XRD if you know the name of the phases.

4- I think the calorimetric studies may help you to get much information about crystallization.

I wish that is useful and help you.

Yours.

Dear Prof. A. Eldenglawey

Thank you so much for your answer, it was really helpful.

I agree with you DSC or DTA may give better indications about these phases.

Thank you so much

have a nice day

With best regards

Yours

Sadeem

 Dear Dr. Carlotta Giacobbe

Thank you so much for your answer, I think this should give the quantitative analysis, however, for glassy phases I think I need to compare the broadening between the standard peaks and the prepared sample peaks, Do you agree?

Best regards
