Ferrophosphorus can be used as a construction aggregate for production of high-density concrete for radiation shielding, as an alternative to usually used steel punchings and shot. It can be used with both Portland cement and magnesia cement. [5] Ferrophosphorus, reacted with sulfur or pyrite, is used for production of phosphorus pentasulfide.
Dry chemical powder is used on all classes of fires. Dry chemical powder puts out the fire by coating the burning material with a thin layer of dust, thereby separating the fuel from the oxygen in the air. The powder also works to interrupt the chemical reaction of fire, so these extinguishers are extremely effective at putting out the fire.
In 2013, Air Products' high purity built-in purifier argon was used to determine a more accurate value for the Boltzmann constant. [10] In September 2015, Air Products announced its intent to spin off its Materials Technologies business. [11] This new stand alone company was named Versum Materials. The spinoff was completed on October 3, 2016. [12]
Genuine Parts Company (GPC) is an American automotive and industrial parts distributor based in Atlanta, Georgia. [1] Established by brothers Carlyle and Malcolm Fraser in 1928, the company has approximately 60,000 employees. [ 2 ]
Phosphoric acid made from elemental phosphorus is used in food applications such as soft drinks, and as a starting point for food grade phosphates. [116] These include monocalcium phosphate for baking powder and sodium tripolyphosphate. [116] Phosphates are used to improve the characteristics of processed meat and cheese, and in toothpaste.

Between 1913 and 1950 radium-228 and radium-226 were used to activate a phosphor made of silver doped zinc sulfide (ZnS:Ag), which gave a greenish glow. The phosphor is not suitable to be used in layers thicker than 25 mg/cm 2, as the self-absorption of the light then becomes a problem. Furthermore, zinc sulfide undergoes degradation of its ...
Phosphate conversion coating is a chemical treatment applied to steel parts that creates a thin adhering layer of iron, zinc, or manganese phosphates to improve corrosion resistance or lubrication or as a foundation for subsequent coatings or painting.
This is used for fluidized bed combustion, chemically reacting the gas with the powder. Some powders may be dustier than others. The tendency of a powder to generate particles in the air under a given energy input is called "dustiness". It is an important powder property which is relevant to powder aerosolization.
