Rheological behavior of aqueous polymer-plasticized γ-LiAlO2 pastes for plastic forming

The rheological properties of aqueous methylcellulose (MC) plasticized γ-LiAlO2 pastes with high solid loading were investigated. A power-law model was applied to characterize torque–shear rate relation of the paste system. The results demonstrated that the power-law model fits well for the aqueous γ-LiAlO2 paste. Thixotropy behavior of the paste was found during shearing, mainly due to linkage break of particle–polymer and polymer–polymer. The rheological study showed that the change of components content has large influence on the thixotropy phenomena and plastic deformation behavior of γ-LiAlO2 pastes. And the rise of temperature caused gelation of MC, leading to the climb of torque value.
