Slip casting using wet-jet milled slurry

Green bodies fabricated by slip casting using wet-jet milled slurries at different solid contents (10, 30, and 50 vol.%), which had low viscosity, had very high relative density and showed very small shrinkage during sintering, as comparing to the ball-milled slurries. The square of the thickness of green bodies was proportional to casting time indicating slip casting was implemented well. The relative density of the green body prepared by the wet-jet milled slurries was 67%, indicating much higher than that of the ball-milled slurries. After sintering, the linear shrinkage of the sintered bodies prepared by wet-jet slurries at different solid contents was constant at 11%. On the other hand, the linear shrinkage of the sintered bodies prepared by the ball-milled slurries was dependent on the solid contents in slurries. Thus, it was possible to produce not only green bodies with high density but also sintered bodies with low shrinkage by using the wet-jet milled slurries.
