Deflagration temperature
The deflagration temperature of a solid or liquid substance is the temperature at which it begins to decompose as a chemical chain reaction . This is characterized by the fact that more energy (binding energy, evaporation energy) is released than was originally supplied. This increases both the reaction rate and the reaction temperature to a typical end value for the substance, which is referred to as the explosion temperature . This temperature is characteristic of the type and quality of an explosive.
Some deflagration temperatures:
| explosive | temperature |
|---|---|
| Acetone peroxide | 130 ° C |
| Urea nitrate | 185 ° C |
| Glycerol trinitrate | 270 ° C |
| Cellulose nitrate | 180 ° C |
| Trinitrotoluene (TNT) | 300 ° C |
