Applications of Nano Pulverization

 · How the Pulverization Process Works. In pulverization, the application of an external force to a particle causes it to elastically deform and then wherever the stress limit of the particle is exceeded, cracks occur at points. It is thought that the particle is destroyed by the propagation of cracks, thus completing the process of pulverization. 2.
