“…When the polymer precursor is heated, side-chain groups will break; organic molecules with low molecular weight will volatilize; dehydrogenation, cross-linking, and polycondensation will occur in the polymer [35]. When temperature is increased to 1000 ℃, pyrolyzing finishes and the remaining product is an inorganic ceramic with an amorphous structure [44]. For the preparation of Si-B-C-N ceramic by this method, five steps are generally required: organic polymer synthesis; distillation, cross linking and curing of the polymer; grinding and shaping of the polymer precursor; pyrolyzing of the shaped precursor at high temperatures in an inert atmosphere; and annealing the as-pyrolyzed ceramic at higher temperatures in an inert atmosphere [3,12,39,[45][46][47].…”

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.

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.

“…Therefore, the design of a new type of high temperature temperature sensor detection system for many harsh environments temperature detection is of great significance.With the development of materials science, a temperature sensor based on SiBCN (silicon boron carbonitride) ceramic material was developed. The sensor is a new type of sensor under the development trend of radio frequency microwave technology, which has good high temperature thermal stability and anti-oxidation [1]. Figure 1 shows a top view and a side cross-sectional view of a SiBCN ceramic sensor.…”

Abstract. SiBCN (silicon boron carbon nitrogen) wireless passive microwave resonant cavity temperature sensor is a new type of sensor under the development trend of radio frequency microwave technology. Based on the working principle of the sensor, the software design of SiBCN temperature sensor wireless sweep transceiver system based on FPGA is carried out on the basis of the existing wireless sweep signal transceiver system hardware. Let the signal source send the 11.0GHz ~ 11.6GHz range sweep signal to the sensor. The feedback signal of the sensor is filtered and the resonant frequency is obtained. The detection of temperature is based on the correspondence between the resonant frequency and the temperature.Through the analysis of the measured results, the system software design meets the requirements, and the temperature and frequency change rate is about 421.2KHz / ℃.
