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.
