ABSTRACT:
A peroxide group containing complex of aluminum, oxygen and hydrogen is obtained having an aluminum/oxygen atomic ratio of about 1:3.
The complex is prepared by reacting, at a temperature below 150.degree. F, aluminum metal of a purity of at least 99.98% by weight with a source of hydrogen ions, such as an aqueous inorganic halogen acid, in the presence of mercury and an oxygen gas-containing atmosphere, the aluminum being partially immersed in the mercury and the source of hydrogen ions, comprising a thin film over the mercury. The thickness of this film is insufficient to cover the aluminum not immersed in the mercury, whereby a portion of the aluminum is exposed to the oxygen gas-containing atmosphere. The complex grows from the exposed surface of the aluminum in the form of an easily frangible self-supporting sheet.
