Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Reference
The CLP Regulation Annex I, section 2.11 states a self-heating substance or mixture is a liquid or solid substance or mixture, other than a pyrophoric liquid or solid, which, by reaction with air and without energy supply, is liable to self-heat; this substance or mixture differs from a pyrophoric liquid or solid in that it will ignite only when in large amounts (kilograms) and after long periods of time (hours or days).
The melting point of indium phosphide is 1062 °C. This shows that the substance is thermodynamically stable at temperatures >1000 °C in air suggesting that it is highly unlikely for indium phosphide to undergo self-ignition.
Indium phosphide is an inorganic substance and does not contain any carbon, hydrogen or oxygen required for combustion.Additionally, indium phosphide has been tested in various synthetic fluids made up of mainly water in which there was no noted reaction with water.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
