Title:
NICKEL PARTICLES AND METHOD FOR PRODUCING SAME, AND ELECTRICALLY CONDUCTIVE PASTE
Document Type and Number:
WIPO Patent Application WO/2016/139967
Kind Code:
A1
Abstract:
Nickel particles contain element nickel as the main component and also contain element copper, and have the following characteristic properties: (a) the average particle diameter of the nickel particles falls within the range from 40 to 150 nm inclusive as observed with a scanning electron microscope; (b) the content of element copper in the nickel particles falls within the range from 0.01 to 2% by weight inclusive; and (c) 20 to 60% inclusive of the counts of detected copper element exist within a radius of 5 nm from the center of each of the nickel particles as determined by a radiation analysis with a scanning electron microscope coupled to an energy dispersive X-ray spectrometer (STEM-EDX) under the condition where the electron beam spot diameter is 1 nm or less.
