Chemistry of Aluminum (Z=13) - Chemistry LibreTexts
Aluminum Oxide and Hydroxide Aluminum oxide is often referred to as alumina or when crystallized, corundum. Aluminum oxide is relatively unreactive because the small Al 3 + ions and the O 2+ form a very stable ionic lattice in cubic closet structure with the ions occupying small octahedral holes.
Aluminum corrosion is commonly encountered when performing chemical process operations involving surface finishing, predominantly in preparation for paint appliion. The protective oxide film of aluminum is only stable in a pH range of 4.5 -8.5.

Reaction of Aluminum with Water to Produce Hydrogen
Introduction: The concept of producing hydrogen by the reaction of certain metals with water was first proposed in the late nineteenth century (1). In more recent times, a paper by Smith in 1972 described an approach using an amalgamated aluminum surface (2).
Environmental Effects and Corrosion on Copper Roofing
After a few weeks of streaking, the calcium hydroxide doesn''t stain copper below it. Unfortunately, the tube may be visually too obtrusive or ugly. Perhaps a perforated copper tube filled with calcium hydroxide treated in a factory to produce a coating of calcium carbonate on the surface would work well.

Titanium - Corrosive Media
Near nil corrosion rates are exhibited in boiling calcium hydroxide, magnesium hydroxide, and ammonium hydroxide solutions up to saturation. Despite low corrosion rates in alkaline solutions, hydrogen pickup and possible erittlement of titanium can occur at temperatures above 170°F (77°C) when solution pH is greater than or equal to 12.

Note: Inhibiting bottleneck corrosion in electrical …
Accelerated calcium corrosion is found at the calcium/electrode junction, leading to an electrical bottleneck. This causes test failure not related to overall calcium loss. The likely cause is a difference in electrochemical potential between the aluminum electrodes and the calcium sensor, resulting in a corrosion element.
