Rheology Study of Suspension Formed by Different Nano-size Y-TZP

The rheological properties of slurries formed by different nano-size Y-TZP have been studied.The viscosity is sensitive to solid loading especially for high solid content level. The dispersant NH4PAA can improve the flowability efficiently. The smaller ceramic particles need to adsorb more dispersant to the flowability. Under the same solid content, the smaller the particles, the higher the viscosity of its slurry
