An illustration of red phosphorus, a chemical element often studied in science classes.

Red phosphorus is a special form of the element phosphorus. It is a red solid that is much safer to handle than another form called white phosphorus. Unlike white phosphorus, red phosphorus does not catch fire easily in the air.

People first made red phosphorus in 1847. A scientist named Anton von Schrötter discovered how to create it by shining sunlight on white phosphorus or by heating it.

Red phosphorus is very useful in everyday life. It is a key ingredient in the safety matches we use at home. When you rub a match against a special surface, red phosphorus helps it light up safely. It is also used in materials that help prevent fires, keeping many things from catching fire too easily.

There are different types of red phosphorus. One type is called violet or Hittorf’s phosphorus. It has a beautiful crystal shape and is made by heating red phosphorus in a vacuum. Another type is called fibrous red phosphorus, which has special chains that help in certain chemical reactions.

Because it is stable and does not react easily, red phosphorus is an important material in science and industry. It helps make many products safer and works as a semiconductor in some technologies.
