EC number: 273-708-2 | CAS number: 69011-71-8 A scum formed on the surface of molten aluminum and molten aluminum alloys.
In accordance with Section 2 of REACH Annex XI, the study does not need to be conducted as the substance decomposes producing flammable gas on contact with moisture. However, data from published literature was used to examine the reaction of Aluminium Nitride with water to produce Aluminium hydroxide and ammonia.
In accordance with Section 2 of REACH Annex XI, the study does not need to be conducted as the substance reacts in contact with water producing flammable gas. The constituents of the substance have no bonds prone to hydrolysis, apart from aluminum nitride. The reaction behavior of AlN with water yielded the following results. Higher temperature and larger surface area of AlN accelerates the hydrolysis The hydrolysis behavior changed at 351 K. Below 351 K crystalline bayerite and NH3 were produced, while crystalline boehmite and NH3 were produced a above 351 K.The hydrolysis of AlN powder was accelerated in NaOH aq and HCl aq in comparison with in deionized water.
