Because phosphorus was used in nerve agents, poisons, and explosives, it is also known as the Devil’s element. The ability to convert atmospheric nitrogen to a form that can be used by plants. Ordinary matches are made by dipping the end of the match into paraffin, then into a wet mixture of phosphorus sulfide, P 4 S 3, lead dioxide or other oxidizing agent, and glue. By far the largest use of phosphorus compounds is for fertilisers. Phosphorus sesquisulfide is used in heads of strike-anywhere matches. The red phosphorus is safe because it is less volatile and less poisonous (0.1 g of white phosphorus can kill a person!) Phosphorus is used to make light-emitting diodes (LEDs). These uses, along with applications in processes such as steel manufacturing and fine china production, make up a small percentage of the uses for phosphorus in the United States. FIRE STARTER: Since phosphorus catches fire readily, it is used in all matches; earlier white phosphorus was used and in today's "safety matches" red phosphorus is used. This form does not ignite spontaneously and is not as dangerous as white phosphorus. The ores are first converted into phosphoric acids before being made into ammonium phosphate. Phosphorus is used to remove oxygen from copper. Phosphorus is used in the production of steel. In 1831, Charles Sauria of France developed a match that used white phosphorus. Human phosphorus use has created problems for wildlife and people, alike. The element also has more nefarious uses. Modern "safety matches," invented in 1844, still use phosphorus, but it is coated on the side of the box and consists entirely of the red allotrope. This form does not ignite spontaneously and is not as dangerous as white phosphorus. Phosphorus is a critical plant nutrient and its key use by phosphate compounds is in the manufacture of fertilizers. It is chemically the least reactive form of phosphorus. As chemical compounds. Phosphorus in the form of phosphate is used in detergents mainly to soften hard water, increase the surface activity of the active washing compounds, raise pH and to deflocculate bigger particles of dirt. Red phosphorus is also used in fireworks, and other explosives. Red phosphorus is used in making pesticides and safety matches. Can be prepared by the action of a silent or spark electrical discharge on the white allotrope. White phosphorus is used in incendiary bombs, smoke screens (such as smoke bombs) and tracer ammunition. Red phosphorus is essential for manufacturing matchbook strikers, flares, safety matches, pharmaceutical grade and street methamphetamine, and is used in cap gun caps. Phosphorus is an important component of DNA and RNA. U.S. President Taft requested that Diamond Match give up their patent. Haber process. Phosphorus compounds synonyms, Phosphorus compounds pronunciation, Phosphorus compounds translation, English dictionary definition of Phosphorus compounds. It should, however, be handled with care as it does convert to the white form at some temperatures and it emits highly toxic fumes of the oxides of phosphorus when heated.

Sodium tripolyphosphate … Look at other dictionaries: phosphorus 32 — thərt ē tü n a heavy radioactive isotope of phosphorus having a mass number of 32 and a half life of 14.3 days that is produced in nuclear reactors and used chiefly in tracer studies (as in biology and in chemical analysis) and in medical diagnos … Medical dictionary. Murders, suicides and accidental poisonings resulted from its use. An essential constituent of protoplasm, it is used in safety matches, pyrotechnics, incendiary shells, and fertilizers and to protect metal surfaces from corrosion. In trace amounts, phosphorus is used as a dopant for N-type semiconductors. Symbol P A highly reactive, poisonous, nonmetallic element occurring naturally in phosphates, especially apatite, and existing in … Black phosphorus is flaky like graphite and is made by subjecting white phosphorus to high pressure. Phosphorus (chemical element) synonyms, Phosphorus (chemical element) pronunciation, Phosphorus (chemical element) translation, English dictionary definition of Phosphorus (chemical element).

Phosphorus compounds are used for fertilizers, soft drinks, … He processed, filtered, and boiled a large amount of urine to isolate the element. You can find red phosphorus on the striking surface of safety match boxes. These matches were strike-anywhere matches and were much easier to ignite. Obtained by Schrotter in 1845 by heating white phosphorus for a few hours at 250° in a flask filled with nitrogen. Phosphorus is used in the making of matches. Red phosphorus is used in matches and flares. Even like there are bio carbon and nitrogen cycles, there is also a phosphorus cycle. It is also used in making alloys. Red phosphorus is used in safety matches, fireworks, smoke bombs and pesticides. It is also used in organic synthesis reactions and in the manufacture of phosphoric acid, phosphine gas and other phosphorus-containing chemicals.
