Abstract

Excellent mechanical properties make γ-Si2AlON3, one of the first spinel sialons and 4-3-spinels, a promising material for structural and abrasive applications. The hardness of this phase synthesized at 13 GPa/1800°C surpasses that of the low-pressure α- and β-sialons, which are used for metal-cutting and engineering applications. The picture shows a γ-Si2AlON3 surface that was used for Vickers hardness testing and indicates the structural relation between β- and γ-sialons and the corresponding phases of Si3N4.
