Risk of explosion in condensed phase

The phenomenon of explosion in condensed phase (liquid or solid) is often referred to by different names, depending on the circumstances in which it occurs.

A thermal explosion means that an exothermic phenomenon has developed, leading to an explosion.

The term "thermal runaway" is frequently used to refer to a particular reaction, which can also be the exothermic decomposition of a substance.

The term "runaway reaction" is also used to describe the loss of control of an identified chemical reaction that was being implemented in a process.

In English, the expressions thermal explosion and especially runaway reaction are used.
