    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: An fixed abrasive article is provided which includes a matrix material and abrasive particles embedded within the matrix material. The abrasive particles have a core-shell structure that includes a polycrystalline alpha alumina core and a shell layer overlying the polycrystalline alpha alumina core. The shell layer includes a material selected from the group consisting of silicon oxide and zirconium oxide. Also the polycrystalline alpha alumina core includes grains and having an average grain size of not greater than about 500 nm.

    Abstract: A boehmite particulate material is disclosed. The material is formed by a process that includes providing a boehmite precursor and boehmite seeds in a suspension, and heat treating the suspension to convert the boehmite precursor into boehmite particulate material. The boehmite particulate material has an aspect ratio of not less than 3:1.
