I have read some literature about the manufacturing of MgB2 by high energy milling of Mg and B. But, I could not find the exact reason why annealing or sintering is needed after high energy milling?
Dear Tejas, By high energy milling you bring atoms to close proximity. To transform the separate atoms (Mg and 2 B) into a molecule, you need to pass an energy barrier. This barrier is passed using heat. Good luck.
Dear Tejas
High energy milling decreases particle sizes of the reactants, increases the uniformity. Also increases reactivity between them by increasing defects on the particle surfaces. It is not easy to form compounds such as MgB2 from its elements just by milling alone. Heating or sintering of milled powders is generally needed to form the compound.
