Silicon Oxycarbide Glasses from Gel Hybrid Structures

Abstract:

Multicomponent (Ti, Zr, Al, B) silicon oxycarbide glasses and nanocomposite materials were derived after pyrolysis of gel hybrid structures in N2 atmosphere. MTES (methyltriethoxysilane) and PDMS (polydimethylsiloxane) were used as precursors for introducing “organic” SiO2. Transformation of the hybrid structure into oxycarbide was followed by SEM, FTIR, 29Si CP MAS NMR, BET analysis. Silicon oxycarbide structure is strongly influenced from the concentration and nature of modifying metal atom.
