Lead styphnate is the primary explosive in modern primers, while barium nitrate is the oxidizer that adds oxygen to the explosive. Tetrazene is a sensitizer that makes the primer easier to detonate. The remaining elements are fuels. The specific ingredients in primer compounds vary from one make to another.
