The method of the present invention overcomes the hot-sticking problems between an inorganic non-metallic material (&equals;insulator) to be molded and a forming die by maintaining an assembly comprising a forming die and the insulator in a polarized state during molding. Processes using said method lead to an improved surface quality of the molded insulator. A device for reducing said hot-sticking comprises a die (,) which acts as conductor, an electrode (,) which may act as support for the insulator (,) to be molded, means (,) for polarizing the assembly of said conductor, insulator and electrode which means (,) are connected by live electric wires (,) with said die and electrode.

Method for reducing hot sticking in molding processes

A composite based on a superconducting oxide having a high critical temperature, characterized by the fact that it is constituted by glass and said oxide, the glass being such that its vitreous transition temperature is not greater than 750K, the volume fraction of the glass lying in the range 2% to 40%, said oxide existing in the glass in the form of crystallites having substantially the same orientation.
