T162 Tabular Alumina Balls are highpurity sintered alphaalumina spheres (in various sizes). This product has been fired at extremely high temperatures (>1900°C) to reduce porosity to a very low level. This hightemperature process leads the growth of large platelike (or tabletlike) alphaalumina crystals giving "tabular" alumina its name.
