The dependence of the sublimation temperature of the soot particles formed in the flames on their size and structure

In this paper, the dependence of sublimation temperature soot particles synthesized during combustion various hydrocarbons, depending on their size and structure, is obtained. The experimental approach based analysis thermal radiation heated to by a nanosecond laser pulse. was measured using two-color pyrometry method. it proposed use average primary compare data in different flames. It established, that depends mainly stage formation, which characterized an increase size. shown, with particle from 12 23 nm, increases significantly 2700 4500 K. This reflects significant difference thermodynamic optical properties so-called "young" "mature" particles, must be taken into account when developing methods diagnostics thermo-physical pyrolysis processes formation soot. Keywords: flames, temperature, structure transmission electron microscopy, laser-induced incandescence.\
