Abstract

Precursors to high-performance ceramics, based on poly(silylene)diacetylene-metal oxide composites see figure, are reported. On thermal conversion under nitrogen, carboreduction and nitridation of the encapsulated metal oxide take place, resulting in the formation of SiC-metal nitride ceramics with well-defined composition profiles.
