    Abstract: Ceramic particulate material includes alumina particles, the particles having a specific surface area (SSA) not less than 15 m2/g and not greater that 75m2/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 that 10% of d50 bij TEM inspection, the concave outer peripheral portion having a negative radius of curvature as viewed from an interior of the particle. Also claimed is a method for forming said ceramic particulare material comprising a hot isostatic pressing of loose powder in order to effect phase transformation of the loose powder.

    Abstract: An abrasive article includes a shaped abrasive particle including a body having a first height (h1) at a first end of the body defining a corner between an upper surface, a first side surface, and a second side surface, and a second height (h2) at a second end of the body opposite the first end defining an edge between the upper surface and a third side surface, wherein the average difference in height between the first height and the second height is at least about 50 microns. The body also includes a bottom surface defining a bottom area (Ab) and a cross-sectional midpoint area (Am) defining an area of a plane perpendicular to the bottom area and extending through a midpoint of the particle, the body has an area ratio of bottom area to midpoint area (Ab/Am) of not greater than about 6.
