May form violently explosive salts in combination with carbon disulfide. The stable allotrope of sulphur at room temperature is _____ . J. Phys. 2NaN3(s)=2Na(s)+3N2(g) a fact: this compound in used in airbags. The nuclei are formed at a rate proportional to the square of the time and, when large, grow at a constant rate with an activation energy of 25 kcal./mole. Explosion is facilitated by the presence of an inert gas above the decomposing liquid. It was of interest, therefore, to examine the effect of pre-irradiation by γ-rays on the isothermal decomposition of barium azide. BARIUM AZIDE, dry or wetted with less than 50% water, by mass . Notice, Smithsonian Terms of Wetting reduces its sensitivity of shock. Ease of decomposition PREVIOUS studies of the decomposition of barium azide have shown1 that the reaction proceeds at the interface between the anhydrous azide and discrete nuclei of metallic barium formed on the surface. Decompositions in the temperature range 27,0°- 100,0°C for barium azide and 30,0° - 90,0°C for strontium azide have been termed photolytic decompositions, while reactions in the temperature range 110,0° - l35,0°C (the thermal decomposition temperature range) for both compounds have been termed co-irradiated decompositions.
