USA Process for producing phosphorus pentoxide or ...
A process for producing phosphorus pentoxide from phosphate ores in a rotarytype kiln includes heating, by exposure to a flame, a porous bed comprising phosphate ore and solid carbonaceous material to a temperature sufficient to reduce the phosphorus pentoxide to phosphorus vapor. The phosphorus vapor is oxidized in an oxidation zone disposed over the porous bed to heat the porous bed.

Properties of Phosphorus | Introduction to Chemistry
White Phosphorus. White phosphorus must be stored in an inert medium away from oxygen, such as in mineral oil, as shown here. White phosphorus is the least stable, the most reactive, the most volatile, the least dense, and the most toxic of the allotropes. It gradually changes to red phosphorus, a transformation accelerated by light and heat.

Oxide Oxides of phosphorus | Britannica
Phosphorus (III) oxide is a white crystalline solid that smells like garlic and has a poisonous vapour. It oxidizes slowly in air and inflames when heated to 70 °C (158 °F), forming P 4 O 10. It is the acid anhydride of phosphorous acid, H 3 PO 3, that is produced as P 4 O 6 dissolves slowly in cold water.
