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]
Phosphoric acid made from elemental phosphorus is used in food applications such as soft drinks, and as a starting point for food grade phosphates. [118] These include monocalcium phosphate for baking powder and sodium tripolyphosphate. [118] 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 ...

Iron phosphate coatings are commonly used in preparation for painting or powder coating, in order to increase adhesion to the iron or steel substrate, and prevent corrosion, which can cause premature failure of subsequent coating processes. It can also be used for bonding fabrics, wood, and other materials to iron or steel surfaces. [citation ...

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.
The Heimlich maneuver is a first-aid method recommended by most health organizations, which uses abdominal thrusts to dislodge an obstruction from a person’s windpipe. Boy, 8, Saves Choking ...
