Hi Ms. Maral.

There are many differences in the morphology, surface area, pore volume, band gap and etc.

The following link can be useful

yes, there is significant difference between these two.

1) The structure and morphology will differ. For example the crystalline structure will vary from one another which can be confirmed by XRD.

2) The pore size and also the surface area will be different from one another.

Calcination means thermal process in air or oxygen
