Effect of lamination conditions for green ceramic tapes on adhesion strength, gas permeability, and yield during binder removal

The trade-off between adhesion strength and gas permeability of green ceramic tapes was examined for tapes laminated at times of 120–600 s, pressures of 1·8–7 MPa, and temperatures of 50–85°C. The dielectric in the green tapes was barium titanate, and the main components in the binder were poly(vinyl butyral) and dioctyl phthalate. The adhesion strength increased with increasing lamination time, pressure and temperature whereas the permeability decreased. The trade-off between permeability and adhesion strength with lamination conditions also influenced the component yield and cycle time for the thermal removal of binder from multilayer green ceramic bodies.
