Abstract : The dependence of the rate coefficients of gas-phase oxidation reactions of metallic species on temperature is discussed. Examples given pertain primarily to Al and B species reactions in the 300 - 1900 K range. These reactions show a wide variety of ln k(T) vs. T to the minus 1 power behavior patterns. It is argued that, because of this variety, it is not yet possible to make reliable predictions regarding reactions for which no experimental data on temperature dependence are available. However, some guidance is given toward making preliminary estimates. Quantitative kinetic data on the discussed reactions are given. The experimental method (HTFFR) used to obtain these data is briefly reviewed.
