Dual-boron-source-modified Polysilazane as a Novel Precursor for SiBCN Ceramics

Here, we demonstrated a novel synthesis of a polyborosilazane （PBSN） precursor using hydrobora- tion and aminolysis reaction synergies to modify polysilazane （PSN）. Specifically, borane tetrahy- drofuran and boron trichloride hexane were used as dual boron sources, which not only reacted with Si-Vi and Si-N-H functionality respectively to mod- ify multiple active sites of PSN resulting in bo- ron-rich silicon-boron-carbide-nitride （SiBCN） ceramics.
