The Route to the Structure Determination of Amorphous Solids: A Case Study of the Ceramic Si3B3N7

“…[22][23][24][25][26][27][28] The discovery of Si 3 B 3 N 7 was seminal to the exploration of a new class of amorphous ceramics for hightemperature applications, in the system Si/B/N/C. [22][23][24][25][26][27][28][29][30][31][32] In spite of their metastable character, these inorganic random networks exhibit high durability under thermal and mechanical loads. They surpass the well-known crystalline ceramics SiC and Si 3 N 4 with respect to the combination of all properties relevant to high-temperature applications in air.…”

Synthesis and pyrolysis of novel polysilazane to SiBCN ceramic

“…6 shows the XRD patterns of the preceramic polymers after pyrolysis with different temperatures. The broad featureless diffraction line at all ranges of 2h typical for amorphous phases suggests that structural transformation is retarded up to 1600°C [25,27,29,30]. The broad peak indicates that the pyrolyzed polymer still maintains an amorphous nature without the formation of crystalline structure.…”

Olefin hydroboration of borazine with vinylsilanes as precursors of Si–B–C–N ceramics

“…We thank to the Korea Basic Science Institute (KBSI) for carry out the 1 H, 13 C, 11 B, and 29 Si NMR investigations.…”

“…Paine and coworkers [11] described the synthetic route of Si-B-C-N polymers by reacting B-chloroborazines with LiSi[Si(CH 3 ) 3 ] 3 followed by the subsequent polymerization with hexamethyldisilazane. Sneddon and coworkers [12] also reported the preparation of Si-B-C-N preceramic polymers via the thermal dehydrocoupling of polysilazanes and borazine.…”
