Abstract (English):
With the use of novel technique of spectral pyrometry, based on registration of continuous spectra of thermal radiation in wide range of wavelength, temperatures within a zone of exothermic reaction of solid-flame combustion have been determined..Under various methods of initiation – laser or microwave – temperatures retain approximately constant value (2500-2600 K). In the case when a plasma formation on the powder surface takes place and different spectra are superimposed, spectral pyrometry gives the possibility to separate of spectra and eliminate both atomic lines and molecular bands in temperature calculation.
