  • Patent number: 6539626
    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.

  • Publication number: 20010006114
    Abstract: The invention relates to a multilayer ceramic moulded part, limited by two virtually parallel surfaces and an edge, which internally contains electrically conductive paths parallel to the surface, characterised in that the moulded part is curved in at least one direction. In particular the invention relates to such a moulded part that is curved in two directions perpendicular to one another. The invention also relates to a process for the production of such a moulded part and to a laminate that is produced as an intermediate in the process.
