PROCESS FOR MAKING CARBON-CONTAINING CERAMICS

A process for carbon-impregnating a refractory porous article,particularly a porous glass article, comprising the steps of impregnating the porous article with a polymerizable furan derivative, polymerizing the furan derivative in situ in the article to form a resin, and firing the article in a nono...

Beschreibung
Zusammenfassung:	A process for carbon-impregnating a refractory porous article,particularly a porous glass article, comprising the steps of impregnating the porous article with a polymerizable furan derivative, polymerizing the furan derivative in situ in the article to form a resin, and firing the article in a nonoxidizing atmosphere to a temperature at least sufficient to convert the resin to carbon, is disclosed. The resulting article has useful thermal and electrical properties.
