Multilayer ceramic green bodies, prepared with barium titanate as the dielectric and poly(vinyl butyral) and butyl benzyl phthalate as the main components of the binder, have been subjected to rapid heating cycles in order to cause failure to occur. In one approach, the heating rate was held constant and the dimensions of the green bodies were varied, while in the second method, the size of the green body was held constant and the heating rate was varied. In all cases, failure of the green body occurred between 115-140 oC. Models were then used to establish that at failure, the binder loading was high and that the internal pressure in the center of the green body was nearly constant, independent of the method used to cause the samples to fail. The internal pressure was then used as an input into a previously-developed algorithm in order to develop rapid debinding cycles without causing component failure.
