Silver chloride (AgCl) is a binary inorganic compound, a white powdery substance. AgCl is a source of silver in chemistry and materials science. In the past, it was the main component of light-sensitive emulsions used in the black-and-white photography. Silver chloride readily decomposes when exposed to visible light, forming metallic silver. This property was the basis for the creation of chloride photographic paper. The reaction can be both the result of visible light exposure and, e.g., the result of high-energy electron beam irradiation. This feature allows observing the process of decomposition in real time directly in the electron microscope chamber. More detail...
