Temperature measurements at the leading edge of the conducting zone of a condensed-system combustion wave

An experimental method is proposed for the estimation of the temperature at the leading edge of the conducting zone in combustion waves in nonconducting condensed systems. Experiments using the Zr + WO$_3$ system demonstrated the effectiveness of the method. The temperature of the leading edge is found to be 2000–2400 K for a combustion temperature of the system of $\approx$ 3000 K.
