Abstract:
1. A process for producing an electroconductive metal-containing material, the process comprising a step of adding water to a water-soluble metal-containing compound to obtain an aqueous solution containing metal ions; a step of adding to the aqueous solution a water-insoluble organic liquid having at least two dispersants different in vaporization temperature dissolved therein; then a step of adding to the aqueous solution a reducing agent with stirring to reduce the metal ions, produce metal-containing particles having their surface coated with the at least two dispersants different in vaporization temperature, and produce a particle dispersion by dispersing in the water-insoluble organic liquid the metal-containing particles having their surface coated with the at least two dispersants different in vaporization temperature; separating the particle dispersion from the aqueous solution; coating an object with a coating containing particles from the particle dispersion; firing the coating at a temperature between the highest vaporization temperature and the lowest vaporization temperature among the vaporization temperatures of the at least two dispersants to produce an electroductive metal-containing material having a volume resistivity of at most 60 μΩcm.
