摘要：

The effect of different dispersants and water leaching on aqueous dispersibility of zirconia powder was studied. Zeta potentials of aqueous solutions containing nano-sized zirconia powder and different dispersants, such as ammonium polyacrylic acid (PAA-NH4) and tetramethyl ammonium hydroxide (TMAH) and water leaching were characterized. Better dispersion of nano-sized zirconia powder in aqueous solutions was achieved with the addition of dispersant and water leaching. (C) 2003 Elsevier Ltd and Techna S.r.l. All rights reserved.
