Ignition temperature silver azide

The ignition temperature is 273°C and is thus much lower than that of lead azide, although the sensitiveness of silver azide to impact is also lower than that of lead azide. Taylor and Rinkenbach [124] report that with a 0.5 kg weight a 77.7 cm drop is necessary to cause detonation of silver azide, whereas for mercury fulminate a 12.7 cm drop is sufficient. 

Silver azide is slightly hygroscopic and is a very vigorous initiator, almost as cllicient as lead azide, Like lead azide, silver azide decomposes under the influence of ultra-violet irradiation. If the intensity of radiation is suflicicntly high the crystals may explode by photochemical decomposition. The ignition temperature and sensitiveness to impact of silver azide are lower than that of lead azide. Some of its properties are presented in Table 2.5. 

After ignition, small crystals of cyanuric triazide bum (unlike silver azide) even though Ficheroulle and Kovache reported them exploding violently by the action of flame [136]. The outcome of initiation by hot wire depends on temperature. At 20-50 °C it only cracks while at 75 °C it explodes [136],... 

Metal Azides. Vapor with silver or sodium azide forms explosive bromine azide.10 Metals. Impact-sensitive mixtures are formed from lithium or sodium in dry bromine.11 Potassium, germanium, antimony, and rubidium ignite in bromine vapor.12 Violent reaction occurs with aluminum, mercury, or titanium.13 Methanol. Vigorously exothermic reaction on mixing the liquids.14 Nonmetal Hydrides. At room temperature, violent explosion and ignition occur with silane and its homologs15,16 and with germane.17... 

To test the theory that metal deposited on the surface of lead azide would act as an electron trap, Reitzner et al. [6] deposited silver on the surface of lead azide. A sensitization was found for both slow and explosive decomposition. Lead nuclei are produced on the surface of lead azide by the action of ultraviolet light with the concomitant production of nitrogen. It has been postulated that the lead nuclei behave at elevated temperatures as electron sinks during the induction period and account for the observed shortened ignition delays [4,7]. 

AMMONIA GAS (7664-41-7) Anhydrous, compressed gas or cryogenic liquid. Difficult to ignite, but can detonate in confined spaces in fire. Reacts violently with strong oxidizers, acids (nitric, hydrochloric, sulfuric, picric, hydrobromic, hydrochlorous, etc.). Shock-, temperature-, and pressure-sensitive compounds are formed with antimony, chlorine, germanium compounds, halogens, heavy metals, hydrocarbons, mercury oxide, silver compounds (azides, chlorides, nitrates, oxides). Fire and/or explosions may be caused by contact with acetaldehyde, acrolein, aldehydes, alkylene oxides, amides, antimony, boron, boron halides.
