Fireproof, electron conducting carrier sleeves for measurement heads intended to detect the oxygen activity, particularly in steel melts. The sleeve (2) has a molecular orientation of graphite platelets of at least 200 mu m in size, which is obtained by means of semi-plastic stamping with reduction of the cross-section area at at least 400 bars, as well as a cold pressure resistance of at least 300 bars obtained after combustion at at least 1,200<o>C. |
