Ultrafeines Nickelpulver

摘要

A nickel ultrafine powder which is characterized by having an average particle diameter of 0.2 to 0.6 mu m and containing coarse particles whose particle diameter is larger than 2.5 times the average particle diameter in an amount less than 0.1% in terms of number-size distribution. It is produced from nickel chloride vapor by reduction with hydrogen in the gas phase. It gives thin internal electrodes (which contributes to high capacity) with only a few short circuits across them.
