Thermal stability and electrical conductivity of carbon-enriched silicon oxycarbide

Abstract

Carbon-rich SiOC can effectively delay phase separation and crystallization during pyrolysis. In air, the SiOC materials are stable up to 1000 °C with <0.5 wt% weight loss. The material has electrical conductivity as high as 4.28 S cm⁻¹ in air and as high as 4.64 S cm⁻¹ in Ar. This semi-conducting behavior and the thermal stability present promising application potentials.
