Summary

The interactive effects of monovalent and divalent salts on suspension rheology of a typical whiteware body were investigated. Salts were chosen that were representative of ions commonly found in industrial whiteware filtrates. It was determined that (a) there were only additive interactive effects between counter-ions and (b) divalent cations dominate the coagulation behavior of whiteware suspensions. It was further determined that the Debye-Hückel approximation can be used to adequately describe the coagulation behavior of clay-based suspensions.
