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.

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: A method of manufacturing a shaped abrasive particle is disclosed. The method includes filling a cavity of a tool with an abrasive particle precursor material. The cavity has at least an interior surface that extends downward from a tool top surface at an angle. The method also includes leveling the abrasive particle precursor material such that a top surface of the abrasive particle precursor materials is flush with the tool surface, such that a sharp portion is formed along the intersection between the sloped wall of the tool cavity and the tool surface and the sharp portion is within the same plane as the tool surface. The method also includes removing a dried abrasive particle precursor from the cavity of the tool. The abrasive particle has a sharp portion formed along the intersection between the interior surface and the tool surface.

Abstract: A method of making elongated abrasive particles includes five steps. Step 1) includes providing a mold having parallel linear grooves, partially interrupted at predetermined intervals by transverse obstructions. Step 2) includes filling the parallel linear grooves with a flowable abrasive particle precursor composition. Step 3) includes at least partially drying the flowable abrasive particle precursor composition to form an at least partially dried abrasive particle precursor composition. Step 4) includes separating that composition from the mold, thereby forming elongated precursor abrasive particles having a shape corresponding to portions of the parallel linear grooves disposed between the transverse obstructions. At least one of the first and second opposite ends of the elongated precursor abrasive particles comprises both a molded portion and a fractured portion. Step 5) converts the elongated precursor abrasive particles into elongated abrasive particles. Elongated abrasive particles preparable by the method and abrasive articles containing them are also disclosed.
