GB/T 46586-2025: This standard establishes the fundamental method for testing the properties of ceramic slurries. It specifies the general procedure for determining their apparent viscosity using a rotational viscometer under a single or a series of constant shear rates. It provides unified specifications for instrument calibration, sample preparation, test conditions, and result reporting for viscosity measurement of ceramic slurries. The measured viscosity data serves as the most direct basis for evaluating slurry fluidity and determining whether it meets the requirements of specific forming processes (such as tape casting or spraying). Together with GB/T 45765-2025 (Thixotropy), it forms a complete evaluation system for the rheological properties of ceramic slurries.
