“…This work inspired a lot of studies to prepare SiCN fibers. In one of these studies, 119) tris(N-methylamino)methylsilane was polymerized at 520°C to deliver a polymer that could be melt-spun at 220250°C. Fibers were hand drawn by touching the surface of the melt with a glass rod and stretching the polymer.…”

High-temperature ceramic materials gain a continuous growing interest due to the various properties they can offer. Among all their specific features, their outstanding thermal and mechanical stability attract much attention to save energy. In the category of ceramics, silicon-based non-oxide compositions display a great potential for many applications involving high temperatures, high stresses or harsh environments. Since the major binary silicon carbide and silicon nitride, which are currently used as highperformance ceramics, were discovered, the role of chemistry in the design of materials has become major. Its potential lies in the exploitation of new chemical systems and the development of new preparative routes. As a consequence, new ceramic properties can be envisioned. The polymer derived ceramic (PDC) route is a "ceramic through chemistry" concept which allows synthesizing new materials in terms of compositions and shapes difficult to tailor using more conventional approaches. This review highlights the works made in the last decades concerning the preparation of PDC fibers with a particular focus on amorphous SiCN and SiBCN networks using melt-spinning and electrospinning processes of preceramic polymers. One main emphasis of this review is set on addressing the intimate relationship between molecular structure/architecture of preceramic polymers, their spinning/ curing/pyrolysis behavior and the properties of the final fibers.

“…It is also reported, that they can be modified by adding other polymers like poly(propylene) or polymethylphenylsiloxane, in the latter case leading to oxygen rich SiC(O) fibers 63, 64. Polycarbosilazanes (Figure 5) are used as precursor polymers for SiCN‐based ceramics and fibers and polysilazanes (Figure 6) are precursor polymers for Si 3 N 4 ‐based materials 5, 65–75…”

Ceramic fibers are essential components of new high‐temperature‐resistant lightweight materials. The production routes of ceramic filament fibers are complex and in most cases polymeric components or structures are key factors for fiber spinning. Either organic polymers are used as additives in the spinning dopes for oxide ceramic fibers or inorganic polymers are the precursors for the production of non‐oxide fibers. This paper gives an up‐to‐date overview about different ceramic fibers and the chemistry behind the fiber development and production.

“…In addition to silicon carbide fibers described above, continuous silicon nitride (Okamura et al, 1987), silicon carbonitride (Legrow et al, 1987;Penn et al, 1982), and silicon oxynitride (Okamura, 1987) fibers have been prepared by the synthesis and pyrolysis of organosilicon polymers. However, at the time of this writing, none of these fibers have been commercialized.…”
