wet jet milling of al2o3 slurries

Abstract: Wet jet milling is a new technology for the pulverization of powders, in which streams of slurry, higher than 100m/s, collide in the channel made of diamond. The effect of processing parameters was investigated in the system of BN/SiO2 mixed powders. The particle size after milling was evaluated by the measurement of BET surface area.

A wet jet milling process was used as a novel method to prepare Al 2 O 3 slurries. The wet jet-milled slurries showed very low viscosity compared with the ball-milled slurries. Moreover, the viscosity of the wet jet-milled slurries was constant for long times, whereas that of the ball-milled slurries increased rapidly with time.

The creep compliance values of the ball-milled, planetary ball-milled, and wet-jet-milled slurries were 5.2 × 10 −3, 1.5 × 10 −3, and 14.8 × 10 3 Pa −1, respectively, indicating that the fluidity of planetary ball-milled slurry was lower than that of the ball-milled one. The fluidity of the wet-jet-milled slurry was fairly strong as ...

These results indicate that Al 2 O 3 particles in the wet jet-milled slurries disperse well for long times and have no tendency to flocculate. In wet jet mill process, mixing and dispersion are carried out only by mutual collision of particles without grinding media.

Abstract In this work, aqueous-based tape casting was used to produce nano-zirconia substrates. Rheological properties of the slurries were measured at room temperature. The acrylic-based suspensions showed a pseudoplastic behavior and remained stable and homogeneous. Warm pressing was used to laminate two or more cast tapes, in order to produce SOFC structures.

Figure 1 shows the particlesize distribution of ball-milled and wet-jet milled ZnO slurries. The mean particlesizes of ZnO samples were 374 and 372nm for ball milling and wet-jet milling, respectively[Fig. 1(a)]. It was almost equal to the primary size of ZnO particles, indicating that it is possibleto. Learn More

Abstract The condition for the preparation of stable nanometer TiO 2 slurries by nonaqueous tape casting was indentified. To acquire stable low-viscosity slurries, the influences of solvent, dispersant and solid content on the rheological properties were investigated. The azeotropic mixtures (ethanol/methyl ethyl ketone) and Polyester/Polyamine Copolymer (KD-1) could …

Al2O3 particles after ball milling yielded more OH groups on the surface. These OH groups were reduced or removed by wet-jet milling following ball milling. Moreover, wet-jet milled slurry after ball milling had lower re-flocculation properties and higher packing density of above 60% than ball-milled slurry. Hence, Al2O3 particles in slurry wet ...
