Phase transformation, oxidation stability, and electrical conductivity of $ TiO_{2} $-polysiloxane derived ceramics
Abstract There have been increasing needs for high-thermal stability and high-electrical conductivity materials. In this study, we in situ synthesized silicon oxycarbide (SiOC)–$ TiC_{x} $$ O_{y} $ composites based on the pyrolysis of polysiloxane and carbothermal reaction between $ TiO_{2} $ nanopa...

| 520 | |a Abstract There have been increasing needs for high-thermal stability and high-electrical conductivity materials. In this study, we in situ synthesized silicon oxycarbide (SiOC)–$ TiC_{x} $$ O_{y} $ composites based on the pyrolysis of polysiloxane and carbothermal reaction between $ TiO_{2} $ nanoparticles and free carbon in SiOC. The $ TiO_{2} $ to $ TiC_{x} $$ O_{y} $ conversion is dependent on the pyrolysis temperature. Higher pyrolysis temperature leads to more TiC formation but lower thermal stability. With more homogeneous distribution of $ TiO_{2} $, the thermal stability of the SiOC–$ TiC_{x} $$ O_{y} $ composite increases. This family of SiOC composite also demonstrates high electrical conductivity. The highest electrical conductivity is 5.03 S $ cm^{−1} $ at 400 °C measurement temperature, the highest for air atmosphere condition. The key issue for tuning the SiOC–$ TiC_{x} $$ O_{y} $ system for both thermal stability and electrical conductivity is to avoid the destabilization of the SiOC system. | ||

Abstract There have been increasing needs for high-thermal stability and high-electrical conductivity materials. In this study, we in situ synthesized silicon oxycarbide (SiOC)–$ TiC_{x} $$ O_{y} $ composites based on the pyrolysis of polysiloxane and carbothermal reaction between $ TiO_{2} $ nanoparticles and free carbon in SiOC. The $ TiO_{2} $ to $ TiC_{x} $$ O_{y} $ conversion is dependent on the pyrolysis temperature. Higher pyrolysis temperature leads to more TiC formation but lower thermal stability. With more homogeneous distribution of $ TiO_{2} $, the thermal stability of the SiOC–$ TiC_{x} $$ O_{y} $ composite increases. This family of SiOC composite also demonstrates high electrical conductivity. The highest electrical conductivity is 5.03 S $ cm^{−1} $ at 400 °C measurement temperature, the highest for air atmosphere condition. The key issue for tuning the SiOC–$ TiC_{x} $$ O_{y} $ system for both thermal stability and electrical conductivity is to avoid the destabilization of the SiOC system. © Springer Science+Business Media New York 2016 |
