Silicon carbonitride ceramics derived from polysilazanes Part I. Investigation of compositional and structural properties

Nearly stoichiometric BN fiber by curing and thermolysis of a novel poly[(alkylamino)borazine]

“…The diffraction pattern [ Fig. 7(c)] only illustrated a diffuse ring pattern of elastically scattered electrons, being characteristic for structures of short-range order [29]. Both were in good agreement with the XRD result above.…”

Review of Net Shape Fabrication of Thermally Conducting Ceramics

“…Non-crosslinked polysilazanes (monosubstituted in some cases) were the widely explored pre-ceramic polymers for fabricating SiC and/or Si 3 N 4 ceramics [67][68][69][70][71][72]. These pre-ceramic polymers were used in the ceramic fabrication in two modes, directly cast [67][68][69][70] or replacement for organic binders [71,72].…”

“…Irrespective of the modes mentioned above, it is prescribed by prior reports to crosslink the oligomeric polysilazane to an infusible solid [68,69]. Compounds like dicumyl peroxide-, potassium hydride-, platinum-, and lithium-based organo-metallic compounds were used as initiators for crosslinking with the concentration ranging between 0.1-1 wt% [71][72][73].…”

Novel binary and ternary phases in the Si-C-N system

“…4). 45)-48) These amorphous silicon carbonitrides are stable up to 1450°C and crystallise into Si3N4/SiC composites at higher temperatures. Crystalline ternary Si-C-N phases obtained via CVD and PVD methods typically possess a modified α -Si3N4 structure.…”
