Sorry, no etymologies found.
As the phosphoric anhydride, or pentoxide, which is produced when a gas containing phosphorus burns, is a solid body, it may be deposited at the burner jets.
For example, vanadium pentoxide (V2O5) is used production of glass and ceramics and as a chemical catalyst.
The majority of vanadium pentoxide used in glass manufacturing is imported from South Africa.
It spontanteously ignites in air at about room temperature to form “phosphorus pentoxide” – actually tetraphosphorus decaoxide, P4O10.
Burning WP produces a hot, dense white smoke composed of particles of phosphorus pentoxide, which are converted by moist air into phosphoric acid.
The White Phosphorus flame produces a hot, dense white smoke composed of particles of phosphorus pentoxide
The White Phosphorus flame produces a hot, dense white smoke composed of particles of phosphorus pentoxide, which are converted by moist air into phosphoric acid.
When exposed to air, it spontaneously ignites and is oxidized rapidly to phosphorus pentoxide.
Anniston the phosphorous was burned in air to produce its pentoxide which could be hydrated to form acid of any desired concentration.
The major plant nutrients (nitrogen, phosphorus pentoxide and potassium oxide) are likely to be about 3% by weight, three times the concentration in compost from municipal refuse.
