GB/T 45765-2025: This standard specifically addresses the thixotropic properties of slurries for fine ceramic forming, stipulating the method for their determination using a rotational viscometer with a controlled shear rate program. The core principle involves measuring the change in slurry viscosity with shear history and its recovery capability through a "three-stage" shear program (low shear - high shear - low shear), quantifying the area of the thixotropic loop or the recovery rate. This directly relates to whether the slurry is easy to handle during processes like slip casting and coating, whether it is prone to sedimentation, and whether it can quickly recover its structure after shear cessation to maintain shape. It is a key rheological indicator for optimizing ceramic slurry formulations and forming processes.
