Get PriceAluminum Oxide - Chemistry LibreTexts
Aluminum oxide is an electrical insulator but has a relatively high thermal conductivity ((30, W m^{-1} K^{-1})) for a ceramic material. It is thus used as insulating material in power electronics. Aluminum oxide is responsible for resistance of metallic aluminum to weathering. Since metallic aluminum is very reactive with atmospheric oxygen, a thin passivation layer of alumina (4 nm ...
