摘要

考虑了露天自传播高温合成（SHS）法制备含游离石墨的多孔碳化钛复合材料的可能性。结果表明，Ti + (1 +)C电荷（x = 0.5, 1.0和1.5）中石墨过量以及压压压力对shs衍生TiC - C复合材料孔隙率、孔隙尺寸以及TiC和石墨颗粒尺寸的影响。给出了炭黑等非晶态碳在多孔TiC-C复合材料的SHS条件下快速石墨化的可能性的直接证明。

SHS of TiC–Graphite Porous Composites and Carbon Graphitization

The possibility was considered of using self-propagating high-temperature synthesis (SHS) in open air to obtain porous titanium carbide composites containing free graphite. The effect of graphite excess in the Ti + (1 + х)C charge (where x = 0.5, 1.0, and 1.5) and pressing pressure on the porosity of the SHS-derived TiC–C composite, as well as on the size of pores and TiC and graphite particles was shown. The direct proof of the possibility of fast graphitization of such amorphous carbon form as carbon black under conditions of SHS of porous TiC–C composites was given.

期刊介绍： International Journal of Self-Propagating High-Temperature Synthesis is an international journal covering a wide range of topics concerned with self-propagating high-temperature synthesis (SHS), the process for the production of advanced materials based on solid-state combustion utilizing internally generated chemical energy. Subjects range from the fundamentals of SHS processes, chemistry and technology of SHS products and advanced materials to problems concerned with related fields, such as the kinetics and thermodynamics of high-temperature chemical reactions, combustion theory, macroscopic kinetics of nonisothermic processes, etc. The journal is intended to provide a wide-ranging exchange of research results and a better understanding of developmental and innovative trends in SHS science and applications.
