Fibrous red phosphorus is another crystalline form of red phosphorus. [7] It is obtained along with violet phosphorus when red phosphorus is sublimed in vacuum in the presence of iodine. [21] It is structurally similar to violet phosphorus. However, in fibrous red phosphorus, phosphorus chains lie parallel instead of orthogonal, unlike violet ...
Violet phosphorus (right) by a sample of red phosphorus (left) Hitorff's phosphorus structure. Monoclinic phosphorus, violet phosphorus, or Hittorf's metallic phosphorus is a crystalline form of the amorphous red phosphorus. [15] [16] In 1865, Johann Wilhelm Hittorf heated red phosphorus in a sealed tube at 530 °C. The upper part of the tube ...

US Air Force Douglas A-1E Skyraider dropping a 100-pound (45 kg) M47 white phosphorus bomb on a Viet Cong position in South Vietnam in 1966 White phosphorus munitions are weapons that use one of the common allotropes of the chemical element phosphorus. White phosphorus is used in smoke ...
The drug can be made from codeine and iodine derived from over-the-counter medications and red phosphorus from match strikers, [17] in a process similar to the manufacturing of methamphetamine from pseudoephedrine. Like methamphetamine, desomorphine made this way is often contaminated with various agents.
Simple mixtures of red phosphorus and potassium chlorate can detonate at a wide range of proportions; a 20% phosphorus mixture had 27% of the equivalent power of a like mass of TNT in a laboratory experiment, and the detonation of the 10% and 20% phosphorus mixtures even in small unconfined samples of 1 gram was described by the authors of one ...
People exposed to white phosphorus can suffer severe and sometimes deadly bone-deep burns. It can cause organs to shut down, and burns on just 10% of the body can be fatal, HRW said.
Phossy jaw, formally known as phosphorus necrosis of the jaw, was an occupational disease affecting those who worked with white phosphorus (also known as yellow phosphorus) without proper safeguards. It is also likely to occur as the result of use of chemical weapons that contain white phosphorus.
Red phosphorus – extremely dangerous, especially in combination with chlorates (Armstrong's mixture); used in caps; also used in matches and some military infrared flares; toxic; White phosphorus – used in incendiary weapons and to make some military smoke screens, ignites spontaneously in air; even more toxic
