For the terrorist, TATP and HMTD offer easy sources of primary explosives. Consulting the do-it-yourself literature, it can be seen that there are two other commonly recommended primary explosives— lead azide Pb(N3)2 and mercury fulminate Hg(ONC)2, but these are difficult to prepare cleanly. The synthesis of diazodinitrophenol (DDNP), common in commercial detonators, is reported in such publications, but apparently is rarely attempted by clandestine chemists. Typically, the brisance of a primary is less than TNT, but the efficacy is the fact that a shock wave can result from a relatively mild insult..

скорость детонации TATP: 5290–5400 m/s это немного выше чем азида.. при значительно, в неск. раз(!) меньшей плотности. На самом деле прим. одинаковая скорость: Ште приводит таблицу для азида 5300--5400 m/s;
DDNP-- еще выше: 6600 m/s по немецким данным,

по теории Зельдовича скорость детонации определяется плотностью ВВ, ну в конденсированной фазе, и только.. хм :)

И далее они пишут про проблемы набивания гильзы азидом свинца, видимо текст писался еще давно, про необходимость введения аморфного азида:

The introduction of LA into commercial detonators resulted in an unacceptably high level of explosions during manufacture and use and hence its use was discontinued until it could be prepared in less sensitive form. A number of methods have been used to prepare LA in a less sensitive form..
Lead azide compositions RD 1343 (improved CMC co-precipitated LA), RD 1352 (improved dextrinated LA)
