Abstract
The combustion of mixtures consisting of titanium powder prepared by SHS hydrogenation and dehydrogenation and black carbon/ boron was studied. It was shown that the oxygen and hydrogen content in Ti powder makes an impact on the combustion characteristics of Ti + C mixtures. It was found that an increase in the hydrogen concentration reduces the combustion temperature, meanwhile, its value is increased with increasing the oxygen content. The mixture with 0.6 wt % hydrogen in synthesized Ti powder did not burn. At 1 wt % oxygen and 0.15 wt % hydrogen, the combustion temperature was showed to reach maximum values, about 3000°C. Contrary to Ti + C mixture, Ti + B mixture components reacted in the SHS mode without additional conditions and the combustion parameters are unaffected by the oxygen and hydrogen content in Ti powder.
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.
