Abstract
Amorphous spherical particles of nickel sulfide of 10 nm in diameter w ere synthesized by the controlled double-jet precipitation (CDJP) tech nique using nickel sulfate and sodium sulfide. Cubic crystalline parti cles of similar to 200 nm were obtained by aging dispersions of amorph ous particles at 80 degrees C for more than a week, as long as the pH was kept between 3 and 3.5. Electrokinetic mobilities of these particl es are reported, as well as color properties of their dispersions in l iquids and in poly(vinyl alcohol) films are described.
