“…Pyrolysis of this precursor at 1000 ℃ in the argon atmosphere produces a kind of Si-B-C-N ceramic, whose structure is amorphous at temperatures lower than 1700 ℃ in air and does not lose weight even at 2000 ℃ in an inert atmosphere. At present, using the polymer pyrolyzing route, various kinds of Si-B-C-N ceramics can be prepared, such as bulk ceramic, ceramic fiber, ceramic coating, porous ceramic, ceramic matrix composite or ceramic microdevice [16][17][18][19]. These products have found potential applications in aerospace craft, traffic transport system, and micromachine or microcircuit used at elevated temperatures, etc [20].…”

Abstract:In the past twenty years, Si-B-C-N ceramic has attracted wide attention due to its special structure and outstanding properties. The ceramic generally has an amorphous or a nano-crystalline structure, and has excellent structural stability, oxidation resistance, creep resistance and high-temperature mechanical properties, etc. Thus, Si-B-C-N ceramic attracts many researchers and finds potential applications in transportation, aerocraft, energy, information, microelectronics and environment, etc. Much work has been carried out on its raw materials, preparation processes, structural evolution, phase equilibrium and high-temperature properties. In recent years, many researchers focus on its new preparation methods, the preparation of dense ceramic sample with large dimensions, ceramic matrix composites reinforced by carbon fiber or SiC whisker, or components with various applications. Research on Si-B-C-N ceramic will develop our insight into the relationship between structures and properties of ceramics, and will be helpful to the development of novel high-performance ceramics. This paper reviews the preparation processes, general microstructures, mechanical, chemical, electrical and optical properties, and potential applications of Si-B-C-N ceramic, as well as its matrix composites.

“…The structural basis of these compounds is provided by polymeric or cyclic silazanes that are cross-linked via C-B-C bridges 8,[55][56][57][58][59][60] or N-B-N units. [61][62][63][64][65][66][67] Another route for the synthesis of Si-B-C-N ceramics is by means of thermolysis of borazine-based oligosilazanes 2,6,[68][69][70][71][72][73] or boron-modified polysilylcarbodiimides.…”

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.
