Abstract
The elaboration of a new type of laminar ceramic-ceramic material is presented. The problem of constrained sintering that follows is adressed : densification kinetics of free samples and constrained powder films are studied and analysed. A microstructural model where the "pore size" evolution is considered, has been developed. A good description of the densification kinetics is then obtained. The lower sintering rate of the constrained layer is mainly due to pore coalescence phenomena.
