This semester, in the Nanoscience Lab, I was required to prepare alpha-Fe2O3(Hematite) by sol-gel method for my first experiment. This was a great experience as I learned a lot of new stuff and got to use cool instruments during the labs. Using my knowledge, and whatever I learnt, I have tried to create a detailed lab manual for the experiment for future students.
To prepare alpha-Fe2O3 nanoparticles by sol-gel technique and study the effect of different annealing temperatures and heating times on the crystallite size using the peak widths of the diffractograms(XRD) of the differently prepared
Here I am attaching a PDF version of the Lab Manual that I created. This is the version 2.0.
It contains observations about all the 4 samples. However, there are still some things that I need to add like the interplanar spacings and lattice parameter calculations and some info in the Results and Discussion section.

Currently, the manual contains info about 2 samples, but it will be updated soon.
