Add to ORKGIn this work, the High Temperature Annular Shear Cell (HT-ASC) was used to characterize the flow properties of two ceramic powder samples with different particle size distributions between ambient temperature and up to 500°C. In particular, it is studied the impact of liquid bridging between particles on the flow properties of the powder. The analysis was carried out on two ceramic powders, provided by an industrial partner and named “A” and “B”
