Aluminum etchants | Transene

Etching time is dependent upon the etchant temperature and the aluminum film thickness. When etching thick aluminum films, a higher etch rate is required; thus a higher etchant temperature should be used. Likewise, for thinner aluminum films, slower etch rates are desired and a lower etchant temperature should be chosen.

Aluminum Oxide Growth Rate as a Function of Partial ...

aluminum oxidizes at different partial pressures of oxygen. Even if the mirror is coated in orbit, it will still come in contact with some oxygen. If the oxide growth rate is too high, it may be necessary to choose a material other than aluminum. If the aluminum is coated with another material, scientists need to know if
