Buy Phosphorus Red
Red phosphorus is obtained by prolonged heating of white phosphorus at high temperatures (250-300 ° C) without air. The color of the substance varies from purple-red to violet.
Red phosphorus, unlike its more well-known “brother”, white phosphorus, is a solid, does not luminesce, is practically insoluble in anything (neither in water, nor in organic solvents, nor in carbon disulfide). It is not poisonous, ignites spontaneously in air only at a temperature of + 240-260 ° C (in fact, it is not red phosphorus itself that ignites, but its vapors, which, after cooling, turn into white flammable phosphorus).
The density of red phosphorus is higher than that of white and is equal to 2.0 – 2.4 g / cm3 (depending on the specific modification).
In the air, red phosphorus absorbs moisture, oxidizes, turning into an oxide; continuing to absorb moisture, it turns into thick phosphoric acid (“soaks”). In view of this, the reagent should be hermetically sealed, depriving access to air moisture. When heated, red phosphorus does not melt, but sublimates (evaporates). After condensation, the vapors of the substances turn into white phosphorus.
Application
The main share of all mined phosphorus (approximately 90%) is used to produce P2O5, it is called thermal phosphoric acid, it is used in the production of various phosphorus fertilizers and various phosphates, including for animal husbandry (mineral top dressing).
Red phosphorus is also used to obtain a variety of phosphorus-containing inorganic and organic compounds.
Red phosphorus has found wide application in the match industry, as the main component of coating the incendiary surface of matchboxes, as a component of thermoplastic compositions, phosphorus is used in the manufacture of incandescent lamps – as a gas absorber.
In the metallurgical industry, phosphorus is used as a deoxidizer in the production of certain alloys, such as chromal, as an alloying additive (phosphorous cast iron contains up to 0.8% P, some steels up to 0.3% P, phosphor bronze up to 1.2% P), as a component solders and antifriction alloys, soft magnetic alloys, for phosphating the surface of steel products in order to increase their corrosion resistance, for obtaining ferromagnesium films in memory elements of computers. Phosphorus of high purity is used to obtain semiconductor phosphides.

Security Requirements
Red phosphorus is not as toxic, but its dust can cause chronic poisoning, as well as pneumonia and skin lesions. Because red phosphorus can ignite, in particular, with friction and impact; it is recommended to break its ingots with Teflon tools.
