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.

セラミックス Al_2O_3 slurries with low viscosity and thixotropic properties which is suitable for slip casting were prepared within a short period of time by adopting wet jet milling process. The viscosity of wet jet milled slurry was about 6mPa・s and remained unchanged for long time, while the viscosity of ball milled slurry rapidly increased with time and ...

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 ...

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 ...

The good dispersion and chemical modification of alumina (Al 2 O 3) nanoparticles as filler were simultaneously performed by a wet–jet milling (WJM) process to disperse the nanoparticles effectively in the polymeric composite.The grafting densities of Al 2 O 3 nanoparticles silane–coupling modified by WJM increased from 0.73 to 1.84 molecules/nm 2 …

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 …

After ball milling with Al 2 O 3 milling balls in a vacuum for 12 h, white Al 2 O 3-doped ZnO (AZO) slurries with good fluidity and viscosity could be obtained. The ball to powder ratio was 2 : 1. The prepared slurries were poured gently into the plaster mould and placed at room temperature for 24 hours.

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.

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

We studied a wet-jet milling process as a novel method to prepare stable ceramic slurries because properties of slurry have an influence on the manufacturing cost, the material characteristics and the reliability of products. The wet-jet milled slurries showed low viscosity and were stable for a long time.

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.

The ability of the wet jet milling method to pulverize nanosized alumina suspensions for sheet casting has been discussed from the point of view of particle?particle separation distance in the slurry. The amounts of polymer additives were optimized to give a stable, ready-to-cast slurry based on rheological measurements. Assuming that the polymers …
