My goal is to counter-check my SEM photo against my XRD data, which the latter (XRD) confirms that I had an almost spherical particle in nanosize scale.
I think my sample is still aggregated in my SEM, could help describe it?
Thank you
Respected Masam,
From SEM it is clear that Hydroxyapetite has flat agglomerated spherical structure. Hydroxyapetite becomes finer when the heating temperature is raised.
Hope this information is useful.

I think your sample shuld be more fine then you can get much more accurate peripheral surface morphology indded.
You can apply controll heat for this optimization particularly.
In the nanoscale, your sample has spheres-like crystals, with bigger-size aggregated crystals. You could control the spherical structure and the aggregation by a controllable heating temperature and try to avoid any cracks resulting from the heating treatment.
I hope my answer is beneficial for you!
Dear Ma. Flynne Dagalea
Morphology, as seen, can be identified as spherical with defects. However, one important noticeable point is Packing Density. It's very well with the above image, and the material should be having good charge transfer properties.
This Hydroxyapatite sample was calcinated at 900-degree celsius, do you think I should lower the temperature so that I can avoid aggregated particle?
The image of SEM shows a spherical and interconnected microstructure, with the presence of a microporous structure similar to that of natural bone, which is desirable for biomedical applications
