Chemoionization and role of charged particles in ignition of monogermanate-oxygen mixtures

Chemoionization was detected in the ignition of monogermanate-oxygen mixtures at initial pressure above 0.25 kPa and a temperature of 290K. The ranges of initial monogermanate concentrations and mixture pressures at which ignition and ionization occur are determined. The concentrations of charged particles ($\simeq$ 6,4 $\cdot$ 10$^{11}$ cm$^3$) and the effective activation energy ($\simeq$ 44 kcal/mole) of the process that limits the ionization rate are estimated. The possible mechanisms of ionization of the reaction mixture were considered. The role of charges in the branching of chain carriers is shown to be negligible.
