Hello.

XRD diffraction can tell you about the crystal structure of the material.

DSC and TG can tell about the losing of mass of the material.

They support each other when you correlate the mass loss with the crystal structure of the material.

Ps: You have some material that can lose water under heating. If you know how much of water you have in your material, you could predict how many events of mass loss you will see. Check the published papers about the material of your interests, and check what they explain for both techniques.

XRPD and DSC can support each other characterisation results, such as crystalline compounds predicted by diffraction peaks in XRPD and melting event in DSC, amorphous materials by "halo" type baseline in XRPD data trace and glass transition by DSC, vice versa. Both can also quantify crystalline or amorphous content in a sample containing both.

Jp Wu please tell me how glass transition in DSC will detect the relation between melting events and crystalline events and how this will help to differentiate between amorphous material and crystalline material?

XRD is excellent for determining the crystal structure and identifying different phases present in a material, while DSC can confirm or provide further insight into phase transitions associated with those phases. For example, if XRD identifies a particular crystalline phase in a material, DSC can be used to study its thermal behavior, such as melting and crystallization temperatures.

Also, DSC is sensitive to changes in the heat flow of a material during phase transitions. When used alongside XRD, DSC can help validate the phase transitions observed in the XRD analysis. For instance, XRD might identify a phase transition, and DSC can then quantify the energy changes associated with that transition.

I hope you find this response fruitful.
