Abstract: A plastic compound (1) comprises at least one organic starting compound (2) of at least one ceramic material (5), and at least one inorganic starting material (3) of the ceramic material (5), the ceramic compound comprising a glass material (4). By subjecting the plastic compound to pyrolysis an electrically insulating glass ceramic (6) having relatively high mechanical stability is obtained. The plastic compound is used as cable sheathing of a cable core. The cable sheathing allows to preserve the functionality of the cable in the case of a cable fire.

Abstract: The invention relates to an aqueous ceramic casting compound which includes a binder made from polyurethane. The casting compound is suitable for producing a very thin ceramic green sheet with a thickness of up to 1 &mgr;m. A mechanical property of the green sheet, such as its modulus of elasticity and tensile strength, can be influenced in a controlled manner with the aid of the binder, so that it is possible for the green sheet to be reliably processed further. A green sheet of this type can be used, for example, to produce a multilayer capacitor with a high capacitance and a low overall height.
