“…bulk ceramic or ceramic fiber prepared by the organic polymer pyrolyzing route, the as-deposited ceramic film prepared by reactive magnetron sputtering, or the as-milled ceramic powder fabricated by mechanical alloying, they all have amorphous structures [17,41,42]. When they are annealed or sintered at temperatures higher than their preparation temperatures, these amorphous ceramics will crystallize into nano composite ones with the phase compositions of B-N-C, SiC and/or Si 3 N 4 [11,37,56]. Generally, the composition homogeneity, structural stability, crystallization process, phase composition and properties of the prepared ceramics are greatly affected by the variation of preparation method, technological process, raw materials or chemical compositions.…”

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.
