Abstract (en)
[origin: DE19752864A1] Brush for transporting electrical current contains an inorganic material(s) that changes its crystalline structure in the region of its melt, sublimation or decomposition range dependent on the temperature. Brush made of carbon or a hydrocarbon filler and a binder matrix for transporting electrical current contains an inorganic material(s) that changes its crystalline structure in the region of its melt, sublimation or decomposition range dependent on the temperature. An Independent claim is included for the manufacture of the above brush by impregnating the porous brush material with a solution or liquid comprising a material(s) that changes its crystalline structure in the region of its melt, sublimation or decomposition range dependent on the temperature and removing the solvent or liquid component.
