Know-how and experience:
The problem of chemical reactivty of fine grained powders appears naturally in cement/gpsum setups.
I have worked with computer modells taking reactivities resulting from grain packageing structures into account to a great extent.
Our main goal was and still is to predict typical microstructures from a few chemical and physical laws.
