Ignition and combustion of titanium particles: experimental methods and results

We have collected and systematized data on patterns and features of the ignition and combustion of titanium in the form of centimeter-sized samples and microparticles with dimensions ranging from several units to several hundred micrometers in the shape of individual particles, air suspensions, and poured and pressed samples. Factors have been identified that affect the temperature and time characteristics of ignition and burning, as well as the composition and dispersity of the formed condensed products, including those in the nanometer-sized 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 metal transforms into oxide.
