Beschreibung
Zusammenfassung:	A process for the production of highly porous glass-ceramic mouldings which contain carbon atoms bonded to silicon atoms is characterised in that a moulding comprising an organopolysiloxane which is solid at room temperature and comprises units of the formula in which R can be a radical of the formulae which is bonded via a silicon-silicon single bond, is reacted under a non-oxidising atmosphere or in vacuo at temperatures in the range from 700 to 1300 DEG C.
