Review of the Synthesis Methods for AIN

Abstract
The different routes for the synthesis of aluminum nitride (AIN) powders are reviewed: the different industrial techniques from both the direct nitridation of aluminum metal and the carbothermal nitridation of alumina, and also other synthesis routes not industrially developed up to now. This paper presents a comprehensive presentation of the different chemical systems analyzed from the compilation of more than 70 publications and analysis of 91 patents.
