| description | A PROCESS FOR PREPARING HIGHLY POROUS GLASS-CERAMIC MOLDED PARTS The invention relates to a process for preparing highly porous glass-ceramic molded parts having carbon atoms linked to silicon atoms, which comprises reacting a molded part, containing an organopolysiloxane which is solid at room temperature, and consists of units of the formula , where R is a radical selected from the formulas or and is linked via a single silicon-silicon bond, in a nonoxidizing atmosphere or in vacuo at temperatures ranging from 700 to 1300.degree.C. |
