Alumina Spherical Powder
Alumina Spherical Powder is a high purity aluminum oxide powder with a spherical morphology. This ceramic powder is available in 41 size variations, from 2 to 1000 microns, with its spherical shape providing advantages for powder flow and packing density compared to angular powders. Alumina Spherical Powder has many applications, including as an abrasive media for surface finishing and polishing, a filler to improve mechanical and dielectric properties of composites, and as a raw material for advanced ceramic components.
