    IPC: C09K3/14

    Abstract: An abrasive article comprises elongated abrasive particles retained in at least one binder. The elongated abrasive particles comprise a ceramic body bounded by at least two longitudinally-oriented contiguous surfaces and first and second ends separated by the at least two longitudinally-oriented surfaces. At least one of the first and second ends comprises both a molded portion and a fractured portion.

    Abstract: The present inventive subject matter provides an abrasive particle. The abrasive particle can include an elongated body that is defined between opposed first and second ends. Each end defines a substantially planar surface. An axis extends through the first and second ends, and each end has a respective first and second cross-sectional area. At least one of the first and second ends is oriented at an angle relative to the axis that is less than 90 degrees. The elongated body has a variable cross-sectional area centered along the axis. At least one cross-sectional area between the first and second ends represents a local minimum cross-sectional area.

    Abstract: A method of making abrasive particles includes: providing a slurry comprising non-colloidal solid particles and a liquid vehicle; forming at least a portion of the slurry into shaped bodies contacting a substrate; at least partially drying the shaped bodies to provide shaped abrasive precursor particles; separating at least a portion of the shaped abrasive precursor particles from the substrate; and converting at least a portion of the shaped abrasive precursor particles into shaped abrasive particles. The shaped abrasive particles comprise alpha alumina having an average crystal grain size of 0.8 to 8 microns and an apparent density that is at least 92 percent of the true density. Each shaped abrasive particle has a respective surface comprising a plurality of smooth sides that form at least four vertexes. Shaped abrasive particles, abrasive articles including them, and methods of using are also disclosed.

    IPC: B24D18/00 ,  B24D11/00

    Abstract: The method generally involves the steps of filling the cavities in a production tool each with an individual abrasive particle. Aligning a filled production tool and a resin coated backing for transfer of the abrasive particles to the resin coated backing. Transferring the abrasive particles from the cavities onto the resin coated backing and removing the production tool from the aligned position with the resin coated backing. Thereafter the resin layer is cured, a size coat is applied and cured and the coated abrasive article is converted to sheet, disk, or belt form by suitable converting equipment.
