METALLIC IMPALPABLE POWDER, MANUFACTURING METHOD THEREFOR, AND CONDUCTIVE PASTE USING THE METALLIC IMPALPABLE POWDER

摘要

PROBLEM TO BE SOLVED: To provide a metallic impalpable powder which has a high sintering initiation temperature and can consequently inhibit delamination, to provide a manufacturing method therefor, and to provide an electroconductive paste. SOLUTION: The metal impalpable powder has an oxide film on the surface formed by ozone gas. The thickness of the oxide film is 1-10 nm. The metal impalpable powder is a nickel impalpable powder. The oxide film is formed by ozone gas. COPYRIGHT: (C)2004,JPO&NCIPI
