Strontium nitrite

Strontium nitrite - Sr(N0 2)2 - is formed as an intermediate in this decomposition reaction, and a substantial quantity of the nitrite can be found in the ash of low flame temperature mixtures [2]. At higher reaction temperatures, the decomposition is... 

P. 0. Ray and N. R. Dhar also measured the electrical conductivities of soln. of the three nitrites and P. C. Ray and 8. C. Mukherjee observed that the degrees of ionization of soln. of calcium nitrite at dilutions t =28-0 and 19-4 litres are respectively 0-84 and 0-82 for strontium nitrite at dilutions v—22-0 and 21-0 litres, 0-84 in both cases and for barium nitrite for c=21-0 and 31-4 litres, respectively 0-84 and 0-86. 

BaAg2(N02)4.H20, from a soln. of the component salts. The formula is here due to M. Oswald, who examined the three nitrites of the alkaline earths, and found only barium forms a double salt. The conditions of stability are represented by AB, Fig. 85. The corresponding diagrams for strontium and calcium nitrites do not show any evidence of the formation of silver strontium nitrite, or of a silver calcium nitrite nor is any strontium barium nitrite formed, for the two salts give a series of mixed crystals, (Ba,Sr)(N02)2.H20. 

A sample of strontium nitrite has been synthesized and thermally characterized by Tuukkanen and coworkers [63] to investigate its role in the ageing of magnesium-strontium nitrate pyrotechnic compositions in the presence of water vapour. Studies by TG-MS and isothermal microcalorimetry showed that the addition of strontium nitrite to a 50% magnesium-50% strontium nitrate composition eliminated the induction reaction normally observed in closed ampoule studies in air at 50 and relative humidities in the range 65-69%.
