Description of key information

A test for auto-flammability is not required. In a study for thermal stability (OECD 113), no endo- or exothermic reaction or self ignition was observed upon heating gallium arsenide powder up to 600°C. The test item is thermally stable up to at least 600 °C and not considered auto-flammable.

Key value for chemical safety assessment
