摘要
The present invention discloses a method for production of nanosilver and nanosilver-coated ceramic powders which comprises adding an aqueous solution of an amine or an alkaline reagent to an aqueous solution of a mixture of silver salt and / or a ceramic powder and educing agent at room temperature to form silver colloids, decanting and drying of the resulting colloidal particles to produce the nano silver powder. The silver-coated ceramic and nano silver powder are useful for making antibacterial plastic, disinfecting ceramic candle filter for water purification and other industrial applications.
