摘要
This paper describes a study of the stability of various aqueous zirconia HSY-8 (Tosoh, Holland) suspensions. The stability is achieved by utilising two commercially available dispersants, namely 'Aluminon' (aurintricarboxylic acid ammonium salt, Fluka Chemicals UK) and 'Tiron' (4-5-dihydroxy-1,3-benzenedisulfonic acid disodium salt, Fluka Chemicals, UK). Rheological, electrophoresis, sedimentation and adsorption measurement have been performed, and are reported, in order to investigate and characterise the stability of these suspensions. A good agreement is reported between the different techniques which identifies the optimum concentration of the corresponding dispersant; that is the condition which provides the most effective degree of sustained particle dispersion. The results for these zirconia suspensions are compared with those of an alumina AES-II (Mandoval Ltd, Surrey, UK). (C) 1998 Published by Elsevier Science Limited. All rights reserved.
