I am preparing Ni-Zn Ferrites by chemical coprecipitation method, the intial reactents being the chlorides of Ni, Zn and Fe. For XRD you need powdered samples and particle size is determined from XRD, so one needs to anneal the samples in powdered form for XRD. Now in order to measure diffrent...

In the case of nanoparticles is there any diffrence on the results (particle size and the other properties that are dependent on particle size) of two similer samples, one of which is annealed after pellet formation and the second sample is annealed in the powdered shape and then pellet is...
