Short Abstract: The work is devoted to the discussion of the principle possibility of metal containing flame diagnostics by its thermal radiation. It is shown that the temperature usually obtained by the multi-color method may be incorrect temperature of oxide particles generated within flame. It is due to the exponential spectral dependence of the emissivity of the emitting oxide particles. It is shown that in the case of real temperature experimentally obtained, the properties of emitting oxide particles differ significantly from bulk material. The substance of these oxide particles contains a large number of defects. This may lead to necessity to take into account the energy of defect formation when calculation of heat evolution at metal combustion
