Abstract:
A process for production of a multilayer ceramic moulded article comprising:a) creating at least one self-supporting ceramic film comprising, i) a binder containing at least one polyolefin having an intrinsic viscosity of at least 5 dl/g as determined at 135Â° C. in decalin, and ii) inorganic solids in an amount of between 40 and 80% relative to total volume of the inorganic solids and binder, wherein said film has a porosity of between 30 and 90%; b) forming at least one electrically conductive path on said at least one ceramic film to form at least one electrically conductive first film; c) forming a composite from, i) said at least one electrically conductive first film formed in b), and ii) at least one second film comprising the ceramic film according to a) or said at least one electrically conductive film according to b), wherein a surface of the first film with the at least one electrically conductive path lies against to the at least one second film, d) subjecting the composite formed in c) to elevated temperature and pressure to form a laminate having a porosity between 10 and 40%, e) deforming said laminate formed in d) under pressure from all sides into a dish shape green moulding comprising at least one curved section, and f) burning out and sintering said green moulding to form the multilayer ceramic moulded article.
