Aluminum Oxide Polishing Powder – Deagglomerated
Aluminum Oxide or Alumina – Aluminum oxide or alumina exists in two allotropic forms (1) alpha, which has a hexagonal crystal structure, and (2) gamma, which has a cubic crystal structure. Alpha alumina removes metal faster and is more suitable for rough polishing, while gamma alumina has slower metal removal rates but produces a better finish. Gamma B (0.05 micron) is used for final polishing steps, typically on a Suncloth Polishing Cloth. Aluminum oxide is excellent for most etch-attack polishing methods.
