Abstract:
Nickel powder comprising, on the basis of the total number of particles, at least 10% of particles whose particle size is at least 1.2 times the average particle size, as determined by SEM observation; and at least 10% of particles whose particle size is not more than 0.8 times the average particle size, as determined by SEM observation; having a coefficient of variation (CV) at least of 30%, in which the CV is determined using an average particle size and a standard deviation obtained on the basis of the Feret diameter as determined by the SEM observation, according to the following equation:CV(%)=((Standard Deviation)/(Average Particle Size))Ã—100; and having a tap density of not less than 2.5 g/cm3.
