FIELD: metallurgy.
SUBSTANCE: invention refers to chemical application of metal coating. The procedure consists in bringing substrate into contact with a bath containing a surface active substance, reducer and metal chosen from a group Ag, Cu, Pd and Co. Also temperature of the bath is higher, than temperature of dimness of solution present in the bath in form of at least two phases. The bath contains water solution of silver salt, substituted alkylene-oxide compound, boric acid, reducer and complex former. The procedure includes silicon surface etching, immersion of silicon surface into the above described bath, leaving silicon surface till silver coating forms on it and extracting silicon surface coated with silver from the bath.
EFFECT: increased visual reflex and electrical conductivity.
