Precious metal powders are produced by various methods, such as for example electrolysis, atomizing from the molten phase, chemical precipitation,

or by cementation with non-precious metals. Depending on the manufacturing process silver powders – as the by far largest volume precious metal powder used – have

Conductive paints and adhesives have broad applications in electrical and electronic engineering. They are used for example for the contacting of film resistors, mounting of terminal wires, conducting electrostatic electricity, or contacting components at low temperatures.
