Abstract
This paper examines the effects of particle concentration and size on the yield stress of ZrO2 suspensions at a well‐defined surface chemistry condition of the isoelectric point (IEP). At the IEP, the relationship between yield stress τYmax and particulate volume fraction φs and mean particle size d was evaluated to be τYmax =Kφs4.0/d2.0. The difference in size distribution of the various ZrO2 suspensions examined causes some degree of scatter in the data used to establish the τYmax, φs, and d relation. The use of particle concentration nt based on the fine size fraction instead of volume fraction φs provided a better correlation, because the fine particles govern the properties of the flocculated network structure.Keywords
