The tape casting is based on ceramic powder mixing in a matrix of binder and plasticizer. Careful consideration must be given to the firing schedule in order to allow the binder and plasticizer will burn out completely.

Thank you Frorian, the experiment in paper not show detail sintering process. Temperature step up have to constrain about 2-3 deg./min, is it? How many the binder and plasticizer adding in to ceramic powder?

Drying of ceramic green tapes is the most difficult procedure in the aqueous tape casting process. Water-based slurry in the drying process is easier to have cracking, curling and to tend segregation of organism and small particles leading to peeling and other defects. Especially it is more obvious that the green bodies dried faster. Therefore, process conditions such as temperature, relative humidity, and air fluid speed should be controlled precisely according to the thickness of green tape, and compositions of slurry, so that the water evaporation rate could be slowed down. The pores in the full tape must be eliminated as much as possible to avoid uneven regional contraction caused by deformation or cracking and green tape curly. The drying rate of the thick tape should be controlled especially in the later stage of drying. The pores are always present in the green tape if the slurry solidifies too fast, which in turn decrease the strength of the green tape and of the sintered sample. Therefore, it is necessary to keep the drying rate within a suitable range.
