Abstract
In this work measurements were taken of the conductivity during detonation of gas suspensions (H2+O2)−Al and O2−Al. The expriments were performed in a shock tube at initial pressures p0=0.2–0.6 atm and with mean volumetric powder densities\(\bar \rho \)=01.–0.5 kg/cm3. The high σ=10−2 to 1 mho/m conductivity exists over an extensive region of the hot reaction products and has a thermal nature.
