Abstract
A process for decreasing the crystallinity of nickel hydroxide by generating and supplying large numbers of heteronuclei into the nickel hydroxide producing reaction system. Nickel sulfate and sodium hydroxide are initially forcefully and intimately combined to form a supersaturated solution of heteronuclei. These heteronuclei are introduced into a nickel powder containing slurry wherein nickel hydroxide having a crystallinity FWHM value of greater than about 0.5° is generated.
