The construction industry is the number one user of phosphogypsum in 2020, with 10.5 Mt used as concrete set retarder and 3.5 Mt used in drywall. [13] It is also used as a chemical feedstock for producing sulfates , and as a soil conditioner similar to regular gypsum. [ 14 ]
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.
Ferrophosphorus can be used instead of zinc powder in some paints and coatings. It has good adhesion, anticorrosive properties, electrical and thermal conductivity, and wear resistance. [7] Ferrophosphorus can be used as a reducing agent to produce sodium or potassium from sodium carbonate or potassium carbonate. [8]

This multipurpose grenade was mostly used for signaling, smoke screens, and inflammation; it could also cause severe burns and had a psychological impact on the enemy. [129] Military uses of white phosphorus are constrained by international law. 32 P and 33 P are used as radioactive tracers in biochemical laboratories. [130]
Electroluminescent displays found, for example, in aircraft instrument panels, use a phosphor layer to produce glare-free illumination or as numeric and graphic display devices. White LED lamps consist of a blue or ultra-violet emitter with a phosphor coating that emits at longer wavelengths, giving a full spectrum of visible light.
The OCP Group (OCP S.A.) (formerly Office Chérifien des Phosphates) is a Moroccan state-owned phosphate rock miner, phosphoric acid manufacturer and fertilizer producer. [2] [3] Founded in 1920, the company has grown to become the world's largest producer of phosphate and phosphate-based products and it is one of the largest phosphate, fertilizer, chemicals, and mineral industrial companies ...
Tritium is the only radiation source used in radioluminescent light sources today due to its low radiological toxicity and commercial availability. [3] Various preparations of the phosphor compound can be used to produce different colors of light. For example, doping zinc sulfide phosphor with different metals can change the emission wavelength ...
