摘要： 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.
摘要翻译： 将模具中的前体α氧化铝磨料颗粒进行干燥处理，使至少大部分前体研磨剂颗粒破裂或破裂成至少两个，从而产生具有比其制造的模具腔更小的尺寸的磨料碎片。 一旦形成的较小的磨料碎片可以像拼图拼图一样重新组装，以再现其制造的模具的原始腔体形状。 认为前体研磨剂颗粒的破裂或断裂是通过确保研磨分散体在模具腔内干燥的情况下，研磨分散体对模具壁的表面张力大于磨料分散体的内吸力而发生的 。

摘要： An abrasive comprising shaped abrasive particles each with an opening. The shaped abrasive particles are formed from alpha alumina and have a first face and a second face separated by a thickness t. The opening in each of the shaped abrasive particles can improve grinding performance by reducing the size of a resulting wear flat, can provide a reservoir for grinding aid, and can improve adhesion to a backing in a coated abrasive article.
