The temperature dependences of the critical reduced electric field strength (E/N){sub cr} in SF{sub 6} and mixtures of SF{sub 6} with C{sub 2}H{sub 6} are obtained in the gas temperature range T{sub g} = 293-1500 K in the absence of thermal dissociation. Gases were heated due to the VT relaxation of SF{sub 6} molecules excited by a pulsed CO{sub 2} laser. The values of (E/N){sub cr} were estimated by the quasi-stationary burning voltage of a self-sustained volume discharge ignited with a delay with respect to the laser pulse. It is shown that in the absence of dissociation, the reduced electric field strength in SF{sub 6} and mixtures of SF{sub 6} with C{sub 2}H{sub 6} in the temperature range under study increases with T{sub g}. The obtained temperature dependence of (E/N){sub cr} in SF{sub 6} is compared with the results reported by other researchers.
