Nb2O5 and Bi2O3 powders were dispersed by anionic dispersants separately and followed by optimized colloidal processing steps to obtain the best mixing results. The influences of the dispersants were investigated by the measurements of zeta-potential

An amphoteric water-soluble copolymer, i.e., poly(acrylamide/(α-N,N-dimethyl-N-acryloyloxyethyl) ammonium ethanate) (PAAM/DAAE), was evaluated as a novel dispersant for aqueous BaTiO3 (BT) slurries. The dispersing property of this copolymer was exam

Pure zirconia, yttria, and three yttria-doped zirconia powders of submicrometer size have been dispersed in various aqueous solutions. The zeta potential (zeta) of the zirconia powders is determined primarily via streaming-current (SC) detection and

In order to understand the reactions of yttria-containing zirconia powder in aqueous solution, the dissolution behavior of yttrium and the formation of the monoclinic (m) phase of the Y-TZP powder were investigated. The tests were conducted in aqueou
