Any other information on results incl. tables

On combustion or on thermal decomposition (following the evaporation of water) the substance releases:

(Carbon oxides (CO + CO2)).

corrosive vapours. (Phosphorus oxides).

Above 200°C releases:(Phosphine)

The phosphine will burn on to phosphorus pentoxide unless there is insufficient fresh air
