Abstract

Polysilocarb formulations, cured and pyrolized materials, was well as articles and use for this material. In particular pyrolized polysilocarb ceramic materials and articles contain these materials where, the ceramic has from about 30 weight % to about 60 weight % silicon, from about 5 weight % to about 40 weight % oxygen, and from about 3 weight % to about 35 weight % carbon, and wherein 20 weight % to 80 weight % of the carbon is silicon-bound-carbon and 80 weight % to about 20 weight % of the carbon is free carbon.
