ABSTRACT:
Thin flat hexagonal silver crystals are formed by rapidly mixing at a temperature of 30.degree.-80.degree. C., a water solution of inorganic silver salt containing a chelating agent for ferric iron with a water solution of ferrous sulfate containing sulfuric acid and additional chelating agent. The preferred chelating agent is phosphoric acid, and the crystals which are formed are stabilized by the addition of a protective colloid such as polyvinyl alcohol.
