Glow of Metals during Anodization in Distilled Water

Аннотация

Study of the anodization of aluminum and tantalum at 1.2 kV in pure (distilled) water showed the possibility of generating electroluminescence (EL) in this system, which excluded the need for introducing any impurities into the initial aqueous medium and simplified interpretation of the observed results. It is established that the products of high-voltage anodization of metals in distilled water and the EL emission accompanying this process are similar to those observed during low-voltage anodization of metals in aqueous electrolyte solutions.
