WebApr 14, 2024 · Heat release rate (HRR) is the principal fire characteristic of materials. There are three known methods for the measurement of HRR (based on oxygen consumption, mass loss rate, and combustion products temperature rise). The method based on oxygen consumption is considered to be the reference. However, this method is expensive and for … WebWhen white phosphorus is burned in excess air or oxygen, phosphorus pentoxide (P4O10) is produced. P4 + 5O2 → P4O10 But when the reaction is carried out in a limited supply of air or oxygen, the major product is phosphorus trioxide (P4O6). P4 + 3O2 → P4O6
