Terminology for compounds in the Si-Al-O-N system

Abstract This document proposes a nomenclature for aluminium silicon oxide nitrides. Introduction : Silicon and aluminium containing nitrides and oxide nitrides are widely studied by the chemical and ceramic community because of the interesting applications, in particular related to their (thermo-) mechanical properties. In the many publications on these materials several abbreviations are used to designate the materials. These relate in part to the processing technology in part to the composition. In the materials community at large and in the ceramic community in particular it is tried to reach agreement upon the use of such acronyms. In the interest of maintaining uniformity in the chemical terms a proposal is made here.
