Abstract (en)
[origin: EP0461866A2] A method of continuously manufacturing an ultrafine spherical nickel powder containing 99.5% or more by weight of nickel in which chemical reaction of nickel chloride vapor and hydrogen is caused by introducing an inert gas into the reaction and controlling the nickel chloride vapor density to about 0.05 to 0.3 in the inert gas while controlling the reaction temperature to about 1,004 DEG C (1,277K) to 1,453 DEG C (1,726K). The ultrafine spherical nickel powder produced is formed of substantially spherical particles having a particle size of about 0.1 to 3 mu m, and contains about 99.5% or more by weight of nickel.
