Rubidium azide is a chemical combination of rubidium and nitrogen .

Manufacturing

Rubidium azide can be made from rubidium carbonate and sodium azide .

${\ displaystyle {\ ce {Rb2CO3 + 2NaN3 -> 2RbN3 + Na2CO3}}}$

Rubidium azide is also formed by the action of nitrogen on rubidium under the influence of an electrical discharge. Rubidium nitride is produced in parallel .

Physical Properties

Rubidium azide crystallizes in the tetragonal crystal system in the space group I 4 / mcm (space group no. 140) with the lattice parameters a = 630.8 pm, c = 753.7 pm, and 4 formula units per unit cell . Template: room group / 140

Chemical properties

The thermal decomposition of rubidium azide at 310 ° C produces rubidium nitride as well as elemental rubidium (60%). However, it's not explosive.
