Abstract

The influence of different organic media and concentrations on the stability of CeO2 particles were investigated. Hydrodynamic sizes in different concentrations revealed that CeO2 particles in ethanol was smaller compared to acetone and methanol. CeO2 particles are negatively charge in ethanol and acetone while positively charge in methanol. Ethanol exhibits a stable suspension over a wide range of concentration from 0.250 mg/mL to 1 mg/mL whereas the CeO2 particles suspended in methanol were all in unstable region due to agglomerated particles and CeO2 particles in acetone were only stable over the short range of concentration from 0.031 mg/mL to 0.250 mg/mL.
