New silver powders with large surface area as heat exchanger materials

The properties of several silver powders made by chemical processing, such as surface area, electrical resistivity and the Kapitza resistance with liquid 3He, have been measured. The results indicate that the finest new powder (C-8), with a large specific surface area (6 m 2 g −1), is suitable for u...

Zusammenfassung:	The properties of several silver powders made by chemical processing, such as surface area, electrical resistivity and the Kapitza resistance with liquid 3He, have been measured. The results indicate that the finest new powder (C-8), with a large specific surface area (6 m 2 g −1), is suitable for use as a heat exchanger material at ultralow temperatures.
