Abstract

During the fabrication of multilayer ceramics, problems have been encountered due to outgassing during the application of heat and the pressure applied by the lamination platens. The present technique avoids the outgassing problem by providing a pair of platens 10 and 12 fabricated from a porous material, such as bronze or ceramic so as to allow outgassing therethrough. The multilayer ceramic is sandwiched between a pair of porous thin elastometer layers 16 and 18, to prevent adhesion of the multilayer ceramic body 20 for easy removal subsequent to the lamination step.
