Phosphorus trioxide is the chemical compound with the molecular formula P 4 O 6. Although the molecular formula suggests the name tetraphosphorus hexoxide, the name phosphorus trioxide preceded the knowledge of the compound's molecular structure, and its usage continues today.
Phosphorus reacts with oxygen, usually forming two oxides depending on the amount of available oxygen: P 4 O 6 (phosphorus trioxide) when reacted with a limited supply of oxygen, and P 4 O 10 when reacted with excess oxygen. On rare occasions, P 4 O 7, P 4 O 8, and P 4 O 9 are also formed, but in small amounts. This combustion gives phosphorus ...

Diphosphorus tetroxide, or phosphorus tetroxide is an inorganic compound of phosphorus and oxygen. It has the empirical chemical formula P 2 O 4 . Solid phosphorus tetroxide (also referred to as phosphorus(III,V)-oxide) consists of variable mixtures of the mixed-valence oxides P 4 O 7 , P 4 O 8 and P 4 O 9 .
Phosphorus oxide can refer to: Phosphorus pentoxide (phosphorus(V) oxide, phosphoric anhydride), P 2 O 5; Phosphorus trioxide (phosphorus(III) oxide, phosphorous anhydride), P 2 O 3; Phosphorus tetroxide, P 2 O 4; Several other, less common, oxides of phosphorus, including P 4 O 7, P 4 O 9, and P 2 O 6; Gases: Phosphorus monoxide, PO ...
Phosphoric acid made from elemental phosphorus is used in food applications such as soft drinks, and as a starting point for food grade phosphates. [113] These include monocalcium phosphate for baking powder and sodium tripolyphosphate. [113] Phosphates are used to improve the characteristics of processed meat and cheese, and in toothpaste.

A trioxide is a compound with three oxygen atoms. For metals with the M 2 O 3 formula there are several common structures. Al 2 O 3 , Cr 2 O 3 , Fe 2 O 3 , and V 2 O 3 adopt the corundum structure .
Phosphorous acid (or phosphonic acid) is the compound described by the formula H 3 PO 3. This acid is diprotic (readily ionizes two protons), not triprotic as might be suggested by this formula. Phosphorous acid is an intermediate in the preparation of other phosphorus compounds.
