Processing route dramatically influencing the nanostructure of carbon-rich SiCN and SiBCN polymer-derived ceramics. Part I: Low temperature thermal transformation

In this study, the significant effect of the processing route on the nanostructure evaluation of carbon-rich SiCN and SiBCN polymer-derived ceramics is reported. For the first time, bulk carbon-rich SiCN and SiBCN ceramics are successfully produced by warm pressing of polyphenylvinylsilylcarbodiimide and polyborophenylsilylcarbodiimide. The bulk samples were compared with their analogous powder samples with respect to the developed...
