Silver azide is a white solid. It forms tiny crystals.

Scientists make it in a lab. They mix silver nitrate with sodium azide in water. This makes the silver azide fall to the bottom as a solid.

The crystals have a special shape. They are made of flat layers. These layers stack on top of each other.

Silver azide is a primary explosive. This means it can explode very easily. A small hit or bright light can make it pop. It can also explode if it gets hot. Pure silver azide explodes at 340 °C. Other bits in the mix can make it explode at 270 °C.

When it explodes, it lets out nitrogen gas. This happens because the solid breaks apart. It makes free electrons and azide radicals. Adding certain oxides can make this happen even faster. This substance is very dangerous. People use a chemical called ceric ammonium nitrate to clean up spills.
