Auto-Ignition Temperature

The auto-ignition temperature is also known as the minimum ignition temperature.

The lowest temperature at which a substance spontaneously ignites in a normal atmosphere without an external ignition source such as a flame or spark.

It decreases with increasing pressure.

Substances that spontaneously ignite in a normal atmosphere at natural ambient temperatures are called pyrophoric.
