摘要：

The properties of several silver powders made by chemical processing, such as surface area, electrical resistivity and the Kapitza resistance with liquid He-3, have been measured. The results indicate that the finest new powder (C-8), with a large specific surface area (6 m2 g-1), is suitable for use as a heat exchanger material at ultralow temperatures.
