In this paper, the gel-tape-casting process was applied to manufacture multilayer green sheets of SiCw /Al2O3 composite. The influence of SiCw, ball milling time and solids loading on the rheological behaviors of SiCw/Al2O3 slurries were investigated. It was found that the slurries exhibited a shear thinning behavior. The viscosity of the slurry increased with increasing of the fraction of SiCw.

In tape casting, the ball-milling time is an important parameter to reach a perfect tape after binder addition. In short milling time, binder is dissolved incompletely, and migrated to the tape surface during drying in long milling time. Both of them deteriorated the quality of green tapes.,,, 3, Vol. Progress 16
