More Information
Summary:The present invention relates to shaped ceramic precursor particles, wherein each shaped ceramic precursor particle comprises a ceramic precursor that can be converted into alpha alumina and is bounded by a surface having a plurality of faces joined along common edges, wherein the surface has voids on at least a portion thereof, wherein the voids are shaped as hollow ellipsoidal sections, wherein the plurality of faces comprises an exposed face having a portion of the voids thereon, wherein the exposed face has a first density of the voids, and a mold face, wherein the mold face has a portion of the voids thereon, wherein the mold face has a second density of the voids, and wherein the first density of the voids is greater than the second density of the voids.
