Combustion regimes of magnesium in carbon oxides. 1. Combustion in CO$_2$

The oxidation and combustion of solitary magnesium particles in a CO$_2$ medium in the range of ambient temperatures 898–1323 K are studied experimentally. A regime of slow heterogeneous combustion that separates the regions of slow oxidation and fast vapor-phase combustion is revealed. The relation between the processes of ignition and combustion of a volatile metal and the structure and properties of the surface film is discussed.
