本文介绍了各种氧化锆HSY-8（Tosoh，荷兰）水悬浮液的稳定性的研究。通过使用两种市售分散剂，即“Aluminon”（金精三羧酸铵盐，Fluka Chemicals UK）和“Tiron”（4-5-二羟基-1，3-苯二磺酸二钠盐，Fluka Chemicals，UK），实现稳定性。流变学，电泳，沉降和吸附测量已经进行，并报告，以调查和验证这些悬浮液的稳定性。一个很好的协议之间的不同的技术，确定相应的分散剂的最佳浓度，这是提供最有效程度的持续颗粒分散的条件。将这些氧化锆悬浮液的结果与氧化铝AES-11（Mandoval Ltd，Surrey，UK）的结果进行比较。
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-11 (Mandoval Ltd, Surrey, UK).
