The grain size of the Nickel Sulphate does not matter since it will be dissolved in de-ionised water, it had high purity. The Nickel powder was arguably showing a mean or mode that matched the suppliers claims and the supplier wasn't claiming a particular surface structure or process, and since Suhas processes it for 100 hours, the scale here is not important. The nickel was highly pure.

The Titanium likewise is to be processed down in scale, however, it needs to be established where the contaminants in this sample originated.
