ABSTRACT:
Silver azide crystals of relatively high bulk density and possessing good flowing and initiating properties are obtained by crystallization from aqueous ammonia solution obtainable by double decomposition of silver nitrate and sodium azide in aqueous ammonia solution. The crystallization is accomplished by distilling the ammonia from the solution until the silver azide begins to crystallize, then adding a small amount of acetic acid to induce formation of crystalline nuclei of silver azide, and continuing the distillation of the ammonia until the silver azide is completely precipitated. The silver azide precipitate thus obtained, when isolated, washed and dried, yields a free-flowing granular product of relatively high bulk density and consisting predominantly of cubical crystals.
