Malonic acid, propionic acid, glycine, n-butylamine, and urea were added to the preparation of nickel phosphate from nickel nitrate and phosphoric acid solutions. These additives were selected from the viewpoint of the functional groups, in short, both acidic sites, one-sided acidic site, acidic and basic sites, one-sided basic site, and both basic sites. Nickel phosphate was not obtained by the addition of glycine. The Ni/P ratio became larger by the addition of n-butylamine. The effect of the addition of acidic and basic compounds was studied on the chemical composition, powder and functional properties of nickel phosphate materials.
