In this report, we discuss the case of a 40 years … White phosphorus looks like a group of tetrahedrons, and requires the minimum amount of temperature and pressure to burn. At room temperature, autoignition will occur and the material will burn violently. M15 White Phosphorous grenade The M15 White Phosphorous grenade is a bursting type grenade used for signaling, screening, and incendiary purposes. Submersion in water stops the white phosphorus/air reaction which however usually resumes when the water is removed. In air, it catches fire at temperatures 10-15 degrees above room temperature. Chemically, white phosphorus is more reactive than red phosphorus; It is polymeric and consists of chains of P 4 tetrahedra linked together as shown in the figure given below; Black Phosphorus properties: α-black and β-black are two forms of black phosphorus. The mainstay of white phosphorus burn treatment is thorough decontamination. It continues to ignite until it is either consumed or deprived from oxygen. The key difference between red and white phosphorus is that the red phosphorus appears as dark red colored crystals whereas the white phosphorus exists as a translucent waxy solid that quickly becomes yellow when exposed to light.. Phosphorus is a chemical element that occurs in several different allotropes.The most common allotropes are red and white forms, and these are solid … When red phosphorus is heated in a sealed tube at 803K, an α-black form is formed. Pure white phosphorus is a colorless-to-white waxy solid, but commercial white phosphorus is usually yellow. WP, or white-phosphorus, when used as an incendiary weapon (i.e., such as a 40mm WP grenade), causes a blast ensued by 'sticky fire.' White phosphorous is pyrophoric, meaning it self-ignites, and can burn clothing, skin, fuel and ammunition. would greatly appreciate any answers..have searched all around, and can't find anything. Often ignites on contact with air; storage under water prevents this reaction. The use of this material as an antipersonnel agent, in incendiary bombs, and as a smoke-producing chemical has intensified the military and industrial problems of control of phosphorus fires. 1946-47]. There are four allotropic forms of phosphorus: two forms of white (or yellow), red, and black (or violet). White phosphorus is also called phosphorus tetramer and has a garlic-like smell.
