Aluminum oxide is an electrically insulating material with high resistivity that increases with purity With its high corrosion resistance, it does not wear easily, even against strong acid. Since aluminum oxide covers all aluminum metal, it is responsible for the metal's resistance to weathering.

Abstract. The electrical characteristics of aluminum (Al) doped zinc oxide (ZnO) thin film for high sensitivity humidity sensors are presented. The effects of Al doping concentration at at % on the Al doped ZnO thin film properties were investigated using current-voltage measurement. The optical and structural properties were characterized using photoluminescence (PL), scanning emission ...
The resistivities of condensed polycrystal and single-crystal aluminum films have been measured as a function of thickness (1600-36000 Å) and temperature (4.2-300°K). Both the temperature-independent residual resistivity and the temperature-dependent resistivity increase with decreasing film thickness. The residual resistivity agrees very well with the Fuchs-Sondheimer theory.

2016-3-17 Aluminium-doped zinc oxide (AZO) ceramic green compacts at a size of 170 × 340 × 17 mm have been prepared by slip casting. An AZO slurry with good fluidity and viscosity was obtained when 1.2 wt% of dispersant was added, which indicates that the slurry prepared with micrometre particles is more suitable for slip casting.
