Popis:	The initiation of exothermic chemical reactions in powder (metal-dielectric) mixtures by irradiating them with a high-power microwave beam is investigated. The initial stage of microwave breakdown is accompanied by the emission in the atomic lines of the metal component of the mixture (Ti, Mo, Sn, Al, etc.). The subsequent microwave discharge generates a continuous optical spectrum, the temperature of the effective Planckian radiator being 2000–3000 K. A prolonged radiation of the mixture after the end of the microwave pulse is caused by the energy release in chemical reactions.
