Abstract: Processes for forming ceramic particulate material. The ceramic particulate material includes alumina particles, the particles having a specific surface area (SSA) not less than 15 m2/g and not greater than 75 m2/g and a sphericity quantified by at least one of (i) a mean roundness not less than 0.710 as measured by Roundness Correlation Image Analysis, and (ii) a concavity less than 20%, wherein concavity is the percent of alumina particles based on a sample of at least 100 particles, which have a concave outer peripheral portion that extends along a distance not less than 10% of d50 by TEM inspection, the concave outer peripheral portion having a negative radius of curvature as viewed from an interior of the particle.

Abstract: Porous ceramic particles can be fragmented by generating a gas inside the pores at a sufficient pressure to cause the particles to be fragmented. The preferred way of generating the pressure is by immersing the particles in a liquid that at ambient temperatures and pressures is a gas until the liquid is absorbed into the pores and thereafter rapidly changing the conditions such that the liquid becomes a gas resulting in explosive fragmentation of the ceramic particles.

Abstract: An abrasive grain is disclosed and may include a body. The body may define a length (l), a height (h), and a width (w). In a particular aspect, the length is greater than or equal to the height and the height is greater than or equal to the width. Further, in a particular aspect, the body may include a primary aspect ratio defined by the ratio of length:height of at least about 2:1. The body may also include an upright orientation probability of at least about 50%.

Abstract: A method of forming a shaped abrasive particle includes extruding a mixture into an opening in a screen within an application zone and translating the screen and belt to a release zone and separating the screen and belt to form a precursor shaped abrasive particle on the belt, wherein the screen and belt are separated at a release angle of at least about 15° and not greater than about 45°, wherein the release angle is defined as an angle between a surface of the screen and a surface of the belt.
