Abstract
The invention relates to a method of manufacturing aluminium nitride, in which a multilayer structure including rolled aluminium-based products is prepared by stacking or winding, and it is heated under a nitrogenous atmosphere, the majority of the nitriding occurring during a phase in which the temperature of the nitrogenous atmosphere is maintained between 400° C. and 660° C. The invention makes it possible to obtain aluminium nitride via an economic method requiring neither the use of aluminium powder as a raw material nor the use of very high temperatures. The aluminium nitride obtained includes particles the microscopic structure of which is layered.
