Abstract

1. Use of cement-free vibratable compositions based on aluminium oxide and/or zirconium dioxide, optionally also with the use of up to 10 wt.% chromium oxide (Cr2 O3 ), silicon carbide (SiC) and/or carbon carriers, and with a content of 2 to 8 wt.%, with respect to the other solid components, of amorphous, finely divided or colloidal silicas as a bonding agent which after shaping and drying have been fired or tempered at temperatures of 300 to 1000 degrees C, for producing components subject to wear in sliding gate valves which come into contact with liquid metals, particularly steel melts.
