Process for forming very thin noble metal flakes comprises forming a dispersed phase of insoluble liq. reducing agent in noble metal salt soln. The salt is reduced to metal flakes at the interface of the soln. and the dispersed reducing agent, and the flakes are recovered. Also claimed is a process for forming noble metal particles by the same method. The process is suitable for producing flakes of e.g. Ag, Au, and Pt. Oxides are formed when less noble metals are used, useful for prodn. of catalysts, pigments and fillers. The process is esp. used to form conductive powders for use in organic resin matrices. Higher conductivity is obtd. using smaller amts. of noble metal. |
