PURPOSE: Provided is a process for producing a multi-functional inorganic composition having conductivity, an antimicrobial property, an electromagnetic wave shielding function, a UV screening function, a far infrared ray emitting function, a bacteria inhibiting function, a moisture controlling function, an air refreshing function. CONSTITUTION: The multi-functional inorganic composition is produced by adding a functional additive to a conventional inorganic composition containing potassium silicate, biostone, an acryl emulsion, a dispersant, wherein the functional additive is inorganic fine particles produced by emulsion-polymerizing an effective amount of a functional additive being silver or copper, 50-90wt% of an inorganic filler being at least one or two selected from sodium silicate, potassium silicate, sodium- or potassium-based colloidal silica, aluminium hydroxide, and etc, 0.01-2wt% of a non-ionic surfactant being at least one or two selected from an amine oxide, an alkyl ester, and a polysorbate, 0.01-1wt% of an alkali metal salt being at least one or two selected from perchlorates of an alkali metal, and 1-50wt% of an ammonium salt being at least one or two selected from ammonium carbonate, ammonium bicarbonate, ammonium bifluoride, ammonium bisulfate, and etc.
