Description of key information

Autoignition temperature [hexachlorodisilane]: 315°C (EU A.15)

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
315 °C

Additional information

An autoignition temperature of 315°C was determined in a reliable study conducted according to an appropriate test protocol, and in compliance with a known quality system (ISO 17025). In a secondary source to which reliability could not be assigned, an autoignition temperature of 320°C was reported for the substance.
