Abstract
A curved multilayer ceramic moulded part, particularly curved in directions perpendicular to one another, is limited by two virtually parallel surfaces and an edge. Electrically conductive path(s) parallel to the surface are provided internally. The molded part may be produced by deforming a dish-shaped green moulding, formed from a composite of a self-supporting ceramic film having at least one electrically conductive path and at least one additional ceramic film, with or without electrically conductive path(s), to pressure from all sides. The deformed part is subjected to burning out and sintering. The moulded articles are virtually free of defects. Absolute deviation from the average shrinking of less than 2% may be obtained.
