Red phosphorus can be used as a very effective flame retardant, especially in thermoplastics (e.g. polyamide) and thermosets (e.g. epoxy resins or polyurethanes). The flame retarding effect is based on the formation of polyphosphoric acid. Together with the organic polymer material, these acids create a char that prevents the propagation of the ...
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 ...
Phosphoryl chloride is used on an industrial scale for the manufacture of phosphate esters (organophosphates). These have a wide range of uses, including as flame retardants ( bisphenol A diphenyl phosphate , TCPP and tricresyl phosphate ), plasticisers for PVC and related polymers ( 2-ethylhexyl diphenyl phosphate ) and hydraulic fluids.

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]
Meat “Meat is a staple in many people’s diets and is rich in nutrients that may aid hair growth. The protein in meat aids growth and helps repair and strengthen hair follicles,” says Gomer.
Use Separate Bank Account for Each Major Goal. Putting together a separate bank account for each goal is an important hack in your road to a better financial future, Klontz said. Naming them gives ...
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 ...
