Infobox references

Thallium azide, TlN₃, is a yellow-brown crystalline solid poorly soluble in water. Although it is not nearly as sensitive to shock or friction as lead azide, it can easily be detonated by a flame or spark. It can be stored safely dry in a closed non-metallic container.

Preparation

Thallium azide can be prepared by dissolving thallium(I) sulfate in water, and adding sodium azide solution. Thallium azide will precipitate; the yield can be maximized by cooling in a freezer.

Safety

All thallium compounds are poisonous and should be handled with care; avoid breathing any dust or fumes.
