  • Ceramic particulate material and processes for forming same
    Patent number: 8343415
    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.
