New pulverization parameter derived from indentation and dynamic compression of brittle microspheres

Particulates may experience dynamic compression loading during materials handling and processing, which in turn can lead to fracture of the particles. In this study, the dynamic fracture behavior of microspherical particles of soda lime glass (SLG), polycrystalline silica, polycrystalline silicon, barium titanate glass (BTG) and yttrium-stabilized zirconia (YSZ) was characterized with high speed, in situ X-ray phase-contrast imaging to examine...
