Description of key information
Aluminium nitride is a solid inorganic substance, which forms blue-white hexagonal crystals. It has a melting point of 3000 °C, the density at room temperature is 3.255 g/cm³. The test EU A.16 aluminium nitride revealed no self-ignition at temperatures up to 400 ºC. The following particle size distribution could be determined by laser diffraction analysis: D90 <3.2µm; D50 <1.1µm; D10 <0.25 µm.
In a transformation/dissolution test aluminium nitride proved to be slightly soluble, releasing maximum aluminium concentrations of 1087.1 µg/L and total ammonia (NH3) of maximally 2048 µg/L (at 100 mg/L nominal loading after 7 days).
Aluminium nitride is non-flammable and non-explosive under the conditions of the test according to VDI guideline 2263.
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.
