Electrical conductivity measurement in the detonation of gases containing aluminum suspensions

In this work measurements were taken of the conductivity during detonation of gas suspensions (Н$_2$ + O$_2$)–Аl and O$_2$–Аl. The expriments were performed in a shock tube at initial pressures $p_0$ = 0.2–0.6 atm and with mean volumetric powder densities $\bar{\rho}$ = 0.1–0.5 kg/cm$^3$. The high $\sigma$ = 10$^{-2}$ to 1 mho/m conductivity exists over an extensive region of the hot reaction products and has a thermal nature.
