SiCN gels as precursors of non-oxidic silicon ceramics

摘要

The present invention relates to novel SiCN gels, which are obtained by reacting silylcarbodiimides R3Si-NCN-SiR3 (R=alkyl, aryl) with silanes RSiX3 (R=H, alkyl, aryl; X=F, Cl, Br, I), and the use thereof to produce non-oxidic silicon ceramics.
