Shaped, fractured abrasive particle, abrasive article using same and method of making

Precursor alpha alumina abrasive particles in a mold are subjected to a drying process that cracks or fractures at least a majority of the precursor abrasive particles into at least two pieces thereby producing abrasive shards having a smaller size than the mold cavity from which they were made. The smaller abrasive shards, once formed, could be reassembled like jigsaw puzzle pieces to reproduce the original cavity shape of the mold from which they were made. The cracking or fracturing of the precursor abrasive particles is believed to occur by ensuring that the surface tension of the abrasive dispersion to the walls of the mold is greater than the internal attractive forces of the abrasive dispersion as the abrasive dispersion is dried within the mold cavity.
