Red phosphorus:
- Red phosphorus is a typical allotrope of phosphorus.
- It is made up of phosphorus atoms in an amorphous (non-crystalline) network.
- It has been discovered to be more persistent than white phosphorus (another naturally occurring phosphorus allotrope).

Red phosphorus is used in safety matches:
- The friction between the match and the striking surface causes the match to heat up.
- On the friction surface, a small amount of red phosphorus is transformed into white phosphorus.
- Red phosphorus has a low ignition temperature. Thus, it is used in the manufacturing of safety matches.
Red phosphorus is preferred over white phosphorus in the manufacture of matches:
- Because of its tetrahedral structure, which has a substantially less angular strain, red is favored over white .
- Furthermore, white is poisonous, whereas red is not.
