Stannous Chloride - an overview | ScienceDirect Topics

Stannous chloride is a very strong reducing agent that absorbs oxygen from the air. The colorless crystalline solid or the white powder is severely irritating and corrosive, and reacts with alcohols, amines, alkalies, and oxidizers, sometimes with violence; the reaction with hydrogen peroxide is strongly exothermic, even in solution.

Interference color anodizing of aluminum and two-step

A. Interference coloring of anodized aluminum has been introduced to the market since 1984. It is a process which is different from the conventional 2-step electrolytic coloring process. The color effect is due to the interference of visible wavelengths rather than light scattering. Interference colouring is by either a 2-step or 3-step process.
