Homogeneity of Aqueous Al2O3/3Y-TZP Feedstock by Plastic Kneading
The effects of different kneading sequences, chemical additives, and solid loadings to the homogeneity and rheological behavior of the Al2O3/3Y-TZP (ZTA) feedstock were investigated. The properties of the feedstock were analyzed by the torque rheometry, transmission optical microscopy (OM) and scanning and transmission electron microscopy (SEM & TEM). The optimal kneading process was determined when good homogeneity was reached. The concepts of critical solid loading and the homogeneity of two-oxide systems, and the power consumption to reach best microstructure will be introduced and quantitatively analyzed.
