    Abstract: Shaped ceramic articles can be obtained by screen printing the desired shapes from a dispersion of a precursor of the ceramic onto a receiving surface using a transfer assisted technique that applies a differential pressure, at least partially drying the screen printed shapes, and firing them to generate the shaped ceramic articles. Shaped abrasive particles made using lower viscosity sol gels that tended to flow or creep after the screen printing formation were found to have higher grinding performance over screen printed shaped abrasive particles made with higher viscosity sol gels.

    Abstract: By controlling the process parameters and by using a polymeric production tooling having a plurality of mold cavities, different types of shaped abrasive particles selected from the group consisting of abrasive shards, dish-shaped abrasive particles, and shaped abrasive particles with an opening can be produced from the exact same mold. In one embodiment, the mold comprised a plurality of equilateral triangles and fractured precursor abrasive particles, dish-shaped precursor abrasive particles, or precursor shaped abrasive particles with an opening were produced from the same mold.

    Abstract: 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.

    Abstract translation: 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 。

    Abstract: A method of making shaped abrasive particles including forming an abrasive flake comprising a plurality of precursor shaped abrasive particles and a frangible support joining the precursor shaped abrasive particles together; transporting the abrasive flake through a rotary kiln to sinter the abrasive flake; and breaking the sintered abrasive flake into individual shaped abrasive particles. The method is useful to make small shaped abrasive particles having insufficient mass to be efficiently individually sintered in a rotary kiln without joining two or more of the shaped abrasive particles together.
