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: 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: Disclosed is a surface coating solution comprising: a water-based solution including polymer in an emulsion; and activated boehmite particles provided in the water-based solution, the boehmite particles comprising mainly anisotropically shaped particles having an aspect ratio of at least 3:1; wherein the surface coating solution has flow and levelling of at least 6; wherein the surface coating solution has a sag resistance greater than 7 mils. The activation of the boehmite particles may be achieved by formation of salts with surface nitrates located on the boehmite particles or adding amines. Ammonium hydroxide, alkali and alkali earth metal salts such as magnesium sulfate and calcium sulfate, thickening clays such as nanoclays, or colloidal silica may be added to activate the boehmite particles. Activation may be carried out by adding substrate particles having surface charge opposite that of the boehmite particles (e.g., colloidal silica is negatively charged, thereby interacting with positively charged boehmite particles).
