Rheology control of ceramics suspensions

Abstract

Fine particles dispersed in liquids are easily flocculated by colloidal interactions and the viscosity of suspensions are drastically increased. The most primarily factor controlling the flocculation level is the surface chemistry between particle and medium. The suspension rheology is discussed in relation to particle-particle interactions induced by the surface properties and adsorbed substances. Referring to several ceramics suspensions, the new method of rheology control will be introduced as application-oriented techniques.
