NICKEL POWDER AND NICKEL PASTE
Document Type and Number:
WIPO Patent Application WO/2017/056741
Kind Code:
A1
Abstract:
Provided are a nickel powder and a nickel paste which are suitable as inner electrode materials for MLCCs and have excellent binder removability and improved wettability and dispersibility with and in low-polar solvents. A spherical nickel powder in which the number average particle diameter D of primary particles is 1 μm or less. The spherical nickel powder has a sodium concentration of 0.001% by mass or less, a calcium concentration of 0.001% by mass or less and a carbon concentration of 0.05 to 2.0% by mass inclusive, has an infrared absorption peak at 1600 cm-1 as measured with a Fourier transform infrared spectrometer, can exert metallic luster when formed into a pasty form by kneading together with dihydroterpinylacetate, and has a rate of decrease in a carbon concentration of 50% or more when treated with heat at 300ºC under an inert atmosphere.
