摘要
The synthesis parameters and results of investigation of electrical properties of nanopowders produced by a spark erosion of silver electrodes in the air are presented. The powders are composed mostly of metallic silver (52.9 wt. %) and silver nitrate (46.5 wt. %) particles with the size less than 50 nm as determined from the transmission electron microscopy images and their specific surface area is ranging from 4 to 11 m(2)/g. The powder production rate is estimated at 0.4 g/h. The corresponding particulate films demonstrated the ultimate resistivity of 3.10(-4) Omega.cm at room temperature.
