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: 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: Methods of making an abrasive article. Abrasive particles are loaded to a distribution tool including a plurality of walls defining a plurality of slots. Each slot is open to a lower side of the tool. The loaded particles are distributed from the distribution tool to a major face of a backing web below the lower side and moving relative to the tool. At least a majority of the particles distributed from the tool undergo an orientation sequence in which each particle first enters one of the slots. The particle then passes partially through the slot such that a first portion is beyond the lower side and in contact with the major face, and a second portion within the slot. The sequence then includes the particle remaining in simultaneous contact with one of the walls and the major face for a dwell period while the web moves relative to the tool.

Abstract: 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.
