The most widely used primaries contain toxic lead azide， lead styphnate and mercury fulminate。 The use of lead primaries has led to environmental pollution by toxic lead deposition after detonation， and personnel using them have been exposed to health risks during manufacture and use。 Unfortunately， all existing primaries suffer from instability， excessive sensitivity， or toxicity。 One of the modern and principal trends in the development of energetic materials is the search of the so called green environmentally benign primary explosives。 One of the representatives of such green explosives is cyanuric triazide (CTA) or triazine triazide (TTA) and has impact (20 cm)， friction (<50g) and spark sensitivity less than 5mJ。 CTA is exhibited similar explosive characteristics as compared to lead azide (LA)。 More importantly， CTA can be synthesiszed more safely from cyanuric chloride with sodium azide and do not pose health risks to personnel and cause much less pollution to the environment。 However， CTA is envisaged as an effective initiating explosive， it is not employed in practice owing to its high sensitivity with sharp edged crystals morphology。 We report herein a convenient method for preparation of CTA with desired particle morphology and characterization。 Further explored CTA as green primary explosive by conducting various experiments such as sensitivity to thermal， spark & mechanical stimuli， ability of CTA initiation by electrical /flash or heat energy， and capability of initiation of secondary explosive charge etc。 Finally， the performances were compared with the aim of replacement of lead/mercury based primaries in detonators。
