Abstract
In tape-cast products a higher shrinkage is observed in the thickness direction compared to the in-plane shrinkage, which is attributed to an anisotropic green tape microstructure caused by shearing and drying during manufacturing. In the present study, cast tapes composed of spherical particles were investigated experimentally and numerically. The shrinkage behavior was analyzed after binder removal and sintering at different temperatures in all three spatial directions. The correlation between anisotropic shrinkage and microstructure concerning pore orientation and coordination number was discussed. Furthermore, it is shown that the anisotropic shrinkage during binder removal contributes strongly to the total shrinkage anisotropy.
