【 摘 要 】

This experimental study is devoted to the electric and optical phenomena, that becomes apparent during the combustion of the two-layer heterogeneous energetically-condensed solid-phase systems with the (Zr+CuO+LiF)/(Zr+BaCrO4+LiF) structure. It was found that such systems combustion is accompanied by an electric pulse signal generation with duration ∼ 1.0 s at half-width and the maximal amplitude 1.2-1.5 V. The signal arises at the combustion beginning and is continuing to the reaction completion. For the mentioned systems it was firstly registered a flame optical emission from the reaction zone within the visible spectral region (λ ∼ 300-700 nm). The initial (green) mixtures and combustion products were explored by x-ray diffraction and scanning electron microscopy. The combustion experiments were carried out by using a home-made experimental mounting, allowing in on-line regime to record the physical parameters of the energetically-condensed systems during a combustion process.
