Rubidium azide, decomposition

Cesium azide, CsNa, is a white, deliquescent soHd of even higher solubiHty in water than the rubidium salt The saturated solution contains 69.2% RbNa at 0°C and 75.5% at 16°C [62] ethanol dissolves only 0.94% (w/w) at 16°C [62]. The salt transforms at 151°C from a tetragonal to a cubic phase, which melts at 326 C with decomposition [108],t leaving, like rubidium azide, a mixture of metal and nitride [103]. CsNa is not sensitive to mechanical shock. 

Potassium, rubidium, and cesium azides are of particular interest, since they undergo thermal decomposition at higher temperatures with the formation of the free alkali metals and the evolution of nitrogen in accordance with the equation...
