As a preliminary work for investigating the workability of alumina green sheet, mechanical properties of green sheet such as fracture stress, Young's modulus, elongational viscosity, and strain to fracture were investigated. A homogeneous alumina slurry prepared by ball milling was tapecast through the gate opening of 1 mm and at a carrier speed of 30 cm/min to obtain green sheet. The results are summarized as follows: The mechanical properties of the green sheet increased with increasing amount of added organics, but depended little on the degree of polymerization of PVB for the same level of PVB addition. The green sheet exhibits the optimum flexibility at a binder to plasticizer ratio from 1 to 1.5.
