Micrometre-sized Pb(Zr0.53Ti0.47)O-3 (PZT) powder was dispersed in water, stabilized with the ammonium polyacrylate (PAANH(4)) and milled to reduce the particle size. The influence of the pH, the amount of PAANH(4), and the milling time on the zeta potential, the PZT particle size and the particle size distribution was studied. The agglomeration took place regardless the milling time at pH 3. The suspension, containing 5 vol.% of PZT and 5 wt.% of PAANH(4), milled at pH 10 for 240 min, was stable and contained particles with a narrow, log-normal particle size distribution with the median size of 160 nm. The dissociated carboxyl groups from the PAANH(4) interacted with the PZT particles as evidenced by Fourier transform infrared spectroscopy and electosterically stabilized the particles in water at pH 10. The PZT particle size and the stability of the suspension fitted the requirements for the ink, suitable for ink-jet printing. (C) 2013 Elsevier Ltd. All rights reserved.
