Ignition and combustion of titanium particles. Experimental methods and results

Institute of Chemical Kinetics and Combustion, Siberian Branch of the Russian Academy of Sciences, ul. Institutskaya 3, Novosibirsk, 630090, Russian Federation

We have collected and systematized data on patterns and features of ignition and combustion of the titanium in the form of centimeter-size samples and microparticles with dimensions ranging from several units to several hundred micrometers in the form of individual particles, air suspensions, poured and pressed samples. The factors have been identified that affect the temperature and time characteristics of ignition and burning; the structure and dispersion of the formed condensed products, including those in the nanometer size range. We also present a modern paradigm of the mechanism of burning and formulate the issues to be resolved to gain a better understanding of how the metal transforms into oxide.
