Chemical Name: Corundum

Chemical Formula: Al₂O₃

Corundum Powder Description:

a) Alumina after fusion, in its high temperature phase, is also called corundum or fused alumina. In nature, corundum is the hardest mineral after diamond. Produced by the controlled fusion and crystallization of high quality alumina

b) Corundum powder is a primary abrasive product for polishing of skin, as the product is extremely hard in nature & also its inertness gives better values for Micro-Derm Abrasions. The product is an ideally gamma ray sterilized and it is abundantly used in skin cleaning operations.

c) It is a granular, white, odorless powder. Aluminum oxide is the highest oxidation state of aluminum and its essentially chemically inertness complies to the micro derm abrasions.

Corundum Powder Typical Chemical Properties Available:

a) Al₂O₃= 99.5% and Na₂O= 0.03

b) Corundum powder which is gamma ray sterilized and used in skin cleaning operations.

Corundum Powder Physical Properties Available:

a) FEPA grain sizes available from 8 to 220 F

b) APS range from 42 to 4.5 microns

c) 100 to 250 mesh for skin cleaning & cosmetic surgery
