Red Phosphorus is one of several allotropes of Phosphorus, it is formed by heating white Phosphorus to 300 °C (572 °F) in the absence of air or by exposing white phosphorus to sunlight.
Red Phosphorus exists as an amorphous network. Upon further heating, the amorphous red Phosphorus crystallises.
Red Phosphorus does not ignite in air at temperatures below 240 °C (464 °F), whereas pieces of white Phosphorus ignite at about 30 °C (86 °F). Ignition is spontaneous at room temperature with finely divided material.
Under standard conditions it is more stable than white Phosphorus, but less stable than the thermodynamically stable black Phosphorus
