Gorokhovs'kyj O. Self-propagating interaction of sodium superoxide and peroxide with some sulfates of s-, p-, d- metals

Proceed of self-propagating interaction (SPI) in inorganic peroxide-salt systems. The reactions were investigated by methods of X-ray phase diffraction, DTA, TG, IR spectroscopy and calorimetric analysis. The speed SPI, the phase structure of the products, the sequence and the temperature intervals of the transformations in 16 systems were determined. For sulfates of s-, p-metals - single-stage scheme and d-metals - two-stage scheme of interaction were justified. The principles of the mathematical description of the thermal analysis and SPI were offered. Kinetic characteristics of the reactions were determined. The principles of forecasting SPI and valuation of kinetic parameters were offered. Sphere of use is the creation and the improvement oxygen - generating and recycling air mixes, the synthesis of metal oxides from high thermally stable substances in a mode SPI.
