“…1 They are also important industrially in, for example, seismic explosives, 2 photoresistors, 3 the manufacture of superconductors (where the thermal decomposition of alkali azides is responsible for a more uniform doping and improvement of the super conducting properties 4 ) and sodium azide has been considered as a rapid source of gas for use in air bags in the car industry. 5 Molecular azides are also high energy density materials which constitute a source of molecular nitrogen for a number of spacecraft applications.…”
